Hydrogen Bonding and Common Mistakes
 
09:00
To see all my Chemistry videos, check out http://socratic.org/chemistry Hydrogen bonding can be so confusing, and in this video we talk about some common mistakes. Hydrogen bonds are intermolecular forces between molecules. They form because one atom has a high electronegativity, so it gets a partial negative charge, and the hydrogen gets a partial positive charge.

Hydrogen Bonds - What Are Hydrogen Bonds - How Do Hydrogen Bonds Form
 
02:48
In this video we discuss hydrogen bonds. We cover how do hydrogen bonds form, the different elements that take part in hydrogen bonds, and why doesn't oil and water mix. What are hydrogen bonds? An attractive force called a hydrogen bond can exist between certain molecules. These bonds are weaker than ionic or covalent bonds, because it takes less energy to break these types of bonds, however, a large number of these bonds going on can exert a strong force. Hydrogen bonds are the result of an unequal charge distribution on a molecule, these molecules are said to be polar. If we look at a water molecule, we can see the oxygen atom shares electrons with 2 different hydrogen atoms. So, in total this molecule has 10 protons, 8 from oxygen and 1 each from the hydrogen atoms, and a total of 10 electrons, 2 shared between the oxygen atom and hydrogen atom number one, 2 shared between the oxygen atom and hydrogen atom number 2, and the other 6 non shared electrons from the oxygen atom. So, this water molecule is electrically neutral, but it has a partial positive side, the hydrogen side, and a partial negative side, the oxygen side of the molecule. The electrons are not shared equally within the molecule, as they have a higher probability of being found closer to the nucleus of the oxygen atom, giving that end a slightly negative charge. So, the hydrogen atoms end of the molecule will have a slightly positive charge. These charged ends weakly attach the positive end of one water molecule to the negative end of an adjacent water molecule. When water is in liquid form there a few hydrogen bonds, solid form, many bonds, and when water is steam or gas, there are no bonds, because the molecules are too far apart to form any bonds. Hydrogen bonds only form between hydrogen atoms that are covalently bonded, or bonds where electrons are being shared and not transferred, to an oxygen, nitrogen or fluorine atom. These bonds make water ideal for the chemistry of life. Hydrogen bonds are also important in the structure of proteins and nucleic acids, which we will cover in later videos. So, now we know that water molecules are polar, or have slightly positive and slightly negative ends, and in fact, many lipids, or fats and oils, are not polar. So their molecules share electrons equally in their bonds. So, these are nonpolar molecules. This means that when water and oil come together they do not form bonds with one another. Even when we try to mix them, the water molecules will eventually separate because their polar molecules are attracted to one another and will form hydrogen bonds, separating the water and the nonpolar oil molecules.

Why is water essential for Life to exist on Earth? We are about 60% water - and there are some organisms that are as much as 90% water! What is so important about water? How does it support life? In this video, we discuss the special properties of water that make it the “Solvent of Life.” Chief among these properties is the extensive Hydrogen Bonding between water molecules that make water an extremely cohesive liquid (the molecules stick together). Due to the extensive hydrogen bonding, water has some emergent properties that impact life on Earth in many ways. These include: Cohesion Adhesion High surface tension High specific heat High heat of vaporization Ice Floats (Ice is less dense as a solid than liquid water) For each of these properties, we discuss how they impact living creatures on Earth. ❀❀❀❀❀❀❀❀❀❀ Our series on Biology is aimed at the first-year college level, including pre-med students. These videos should also be helpful for students in challenging high school biology courses. Perfect for preparing for the AP Biology exam or the Biology SAT.

Atomic Hook-Ups - Types of Chemical Bonds: Crash Course Chemistry #22
 
09:46
Atoms are a lot like us - we call their relationships "bonds," and there are many different types. Each kind of atomic relationship requires a different type of energy, but they all do best when they settle into the lowest stress situation possible. The nature of the bond between atoms is related to the distance between them and, like people, it also depends on how positive or negative they are. Unlike with human relationships, we can analyze exactly what makes chemical relationships work, and that's what this episode is all about. If you are paying attention, you will learn that chemical bonds form in order to minimize the energy difference between two atoms or ions; that those chemical bonds may be covalent if atoms share electrons, and that covalent bonds can share those electrons evenly or unevenly; that bonds can also be ionic if the electrons are transferred instead of shared: and how to calculate the energy transferred in an ionic bond using Coulomb's Law. -- Table of Contents Bonds Minimize Energy 01:38 Covalent Bonds 03:18 Ionic Bonds 05:37 Coulomb's Law 05:51 -- Want to find Crash Course elsewhere on the internet?

Ionic and Covalent Bonds, Hydrogen Bonds, van der Waals - 4 types of Chemical Bonds in Biology
 
08:50
There are four types of chemical bonds essential for life to exist: Ionic Bonds, Covalent Bonds, Hydrogen Bonds, and van der Waals interactions. We need all of these different kinds of bonds to play various roles in biochemical interactions. These bonds vary in their strengths. In Chemistry, we think of Ionic Bonds and Covalent bonds as having an overlapping range of strengths. But remember, in biochemistry, everything is happening in the context of water. This means Ionic bonds tend to dissociate in water. Thus, we will think of these bonds in the following order (strongest to weakest): Covalent, Ionic, Hydrogen, and van der Waals. Also note that in Chemistry, the weakest bonds are more commonly referred to as “dispersion forces.” Related Chemistry video: Ionic Bonds vs Covalent Bonds http://bit.ly/2cUG6C8 Our series on Biology is aimed at the first-year college level, including pre-med students.

How Does Water Bond - Covalent Bonds | Chemistry for All | FuseSchool
 
02:40
Learn the basics about the covalent bonding of water, when learning about covalent bonding within properties of matter. Water is made from one oxygen atom and two hydrogens. The oxygen has 6 electrons in its outer shell, but it really wants to have 8 to have a full shell. The hydrogens have one outer shell electron, but want to have two. The atoms share their electrons, forming covalent bonds. So all three atoms have full outer shells, and create a water molecule. Water has two covalent bonds. In water, the bonding electrons spend most of their time nearer the oxygen atom, because it is more ELECTRONEGATIVE. This means that it is electron withdrawing. As the negatively charged electrons are nearer the oxygen atom, the oxygen atom becomes a little bit negative itself, while the hydrogens become a little positive. This is called delta positive and delta negative. Water doesn’t just have any old covalent bonds; it has what we call POLAR COVALENT bonds and is a POLAR molecule. This is really important as it affects how water behaves and reacts with other elements. SUBSCRIBE to the Fuse School YouTube channel for many more educational videos.

Subscribe to watch more online chemistry courses & science videos: http://www.youtube.com/channel/UCiX8pAYWBppIbtUZTfGnRJw?sub_confirmation=1 About Atomic School: Atomic School supports the teaching of Atomic Theory to primary school & science students . We provide lesson plans, hands-on classroom resources, demonstration equipment, quizzes and a Teacher's Manual to primary school teachers. Animated videos that clearly explain the scientific ideas supports learning by both teachers and students. As a teacher, you don't have to look anywhere else to implement this program. Our work has been verified by science education researchers at the University of Southern Queensland, Dr Jenny Donovan and Dr Carole Haeusler, who confirm that primary students are capable of learning much more complex scientific concepts than previously thought, and crucially, that they love it. Students run to class! The program has been trialed in Australian schools as well as schools in the Philippines, Iran and India. It is conducted as holiday workshops at the Australian Nuclear Science and Technology Organisation, the Queensland Museum as well as the World Science Festival. It has attracted wide media interest, including TV, radio and print, and the research data has been presented at prestigious American Education Research Association and Australian Science Education Research Association conferences. Atomic Theory underlies all the other sciences- genetics, electronics, nanotechnology, engineering and astronomy- so an early understanding will set them up for a more successful learning sequence for all their science subjects, and support their mastery of mathematics as well. We also have extension programs that cover Biology, Physics and Astronomy to an equal depth. About Ian Stuart (Email: [email protected]): The founder of Atomic School, Ian Stuart, taught Chemistry and Physics for 25 years at senior levels before he realized that his 8-year old son, Tom, could understand Atomic Theory at a much deeper level than he expected. After visiting Tom's class at school, he discovered that his peers could also grasp the abstract scientific concepts, as well as apply it usefully to the real world. Ian then developed a program to teach the advanced concepts of high school Chemistry, Physics and Biology to students 10 years younger than they normally would. He found that this engaged their interest in modern science early, and sustained it through to high school and beyond. It also sets them up for future success in their academic and career paths. Ian has a Bachelor's Degree in Chemistry from the University of Queensland and a Master's degree in Electrochemistry from the University of Melbourne. Connect with Atomic School on social media: http://facebook.com/AtomicSchool http://twitter.com/AtomicSchools http://instagram.com/AtomicSchools Video transcript: Let's do a thought experiment. Imagine a box filled with hydrogen atoms. Like billiard balls on a pool table, atoms actually move, and they do it in straight lines until they hit something … like another hydrogen atom. Oh! See that? They stuck together. They’re not separate hydrogen atoms any more, but a pair of hydrogen atoms moving together. There goes another pair. 4.1 When atoms join up like this, scientists call it a molecule. And they call the join between them a chemical bond. Here comes another hydrogen atom crashing into the hydrogen molecule. But this time it doesn’t stick. Instead it just bounces off. Hydrogen atoms bond once, and that’s it. They’re just like that. Pretty quickly all the hydrogen atoms will collide and pair off into molecules. They will keep hitting each other, but they'll just bounce off. Scientists like to have a shorthand way of writing this molecule thingi. Here’s one way to show it, with the hydrogen symbols joined by a stick to show the chemical bond between the atoms. Another way is to write H2, with the little 2 after the H and a bit lower. A number written this way is called a subscript. What do you think the 2 stands for? It counts the number of hydrogen atoms in the molecule. Easy, heh! So when we have a balloon filled with hydrogen gas, it really contains trillions of trillions of H2 molecules. Let's do another thought experiment. We'll go back to our box filled with hydrogen atoms, but this time put an oxygen atom in there too. When a hydrogen atom crashes into an oxygen atom, they stick together. But wait, when another hydrogen atom hits, it also sticks to the oxygen. What about a third hydrogen atom? No, that’s if for oxygen. It can only make 2 bonds and then it’s done.

Examples and practice problems include the following molecules: H2O, CH4, CH3F, HF, CH3OH, CH3OCH3, CH3COOH, CH3CHO, H2S, NH3, PH3, (CH3)3N, (CH3)2NH, C2H4, C2H2, HOCH2CH2OH, CH3SH, and CH3CONH2. This video also discusses the difference between a hydrogen bond and a covalent bond and the difference between an intermolecular bond and an intramolecular bond. it shows the formation and hydrogen bonding that occurs between water molecules.
Types of Hydrogen Bonds | Intermolecular and Intramolecular Bonding
 
03:52
There are two different types of hydrogen bonds. They are Intermolecular bonding and Intramolecular bonding. i) Intermolecular hydrogen bonding. This type of bond is formed between the two molecules of the same or different compounds. Some examples of the compounds exhibiting intermolecular hydrogen bonds are : Hydrogen fluoride and water. 1. Hydrogen fluoride, H F. In the solid state, hydrogen fluoride consists of long zig-zag chains of molecules associated by hydrogen bonds as shown in the figure. Therefore, hydrogen fluoride is represented as HFN. 2. Water In water molecule, the electronegative oxygen atom forms two polar covalent bonds with two hydrogen atoms. The oxygen atom due to its higher electronegativity acquires partial negative charge and the two hydrogen atoms acquire partial positive charge. The negatively charged oxygen forms two hydrogen bonds with two positively charged hydrogen atoms of two neighbouring molecules. Each oxygen atom is tetrahedrally surrounded by four hydrogen atoms as shown in visual. Hydrogen bonding in water results in a hydrogen bridge (HOH) network extending in three dimensions and the associated water molecule may be expressed as H Two O N. ii) Intramolecular hydrogen bonding. This type of bond is formed between hydrogen atom and Nitrogen, Oxygen or Flurine atom of the same molecule. This type of hydrogen bonding is commonly called chelation and is more frequently found in organic compounds. Intramolecular hydrogen bonding is possible when a six or five membered rings can be formed. Importance of H-bonding i) Life would have been impossible without liquid water which is the result of intermolecular H-bonding in it. ii) Hydrogen bonding increase the rigidity and strength of wood fibres and thus makes it an article of great utility to meet requirements of housing, furniture, etc. iii) The cotton, silk or synthetic fibres also own their rigidity and tensile strength to hydrogen bonding. iv) Most of our food materials such as carbohydrates and proteins also consist of hydrogen bonding. v) Hydrogen bonding also exists in various tissues, organs, skin, blood and bones.

Water and Hydrogen Bonds (The Importance for Living Organisms)
 
06:01
The polar nature of water gives it some important properties. It allows things to dissolve in it. It has a high specific heat capacity. It’s got a high heat of vaporisation. Water molecules are cohesive meaning they can stick to each other. They are adhesive meaning they can stick to other things. Water has a high surface tension. And because hydrogen bonds force solid water to form in a crystalline structure, ice is less dense than water and therefore it floats.

Hydrogen Bonds In Water Explained - Intermolecular Forces
 
10:54
This chemistry video tutorial provides a basic introduction into hydrogen bonding. Hydrogen bonding occurs in molecules when hydrogen is attached to highly electronegative small atoms such as nitrogen, oxygen, and fluorine. Hydrogen bonds are very strong dipole dipole interactions. Molecules that contain hydrogen bonds such as water are very polar. Hydrogen bonds is one of the strongest types of intermolecular forces. This video contains a few examples and illustrations of hydrogen bonds in water and in HF.

What Are Intermolecular Forces | Chemistry for All | FuseSchool
 
05:19
Learn what intermolecular forces are, the three most common types and the differences between them. An intermolecular force is simply an attractive force between neighbouring molecules. There are three common types of intermolecular force: permanent dipole-dipole forces, hydrogen bonds and van der Waals' forces. All these three forces are very much weaker than ionic or covalent bonds which bind atoms and ions together in elements and compounds. Permanent dipole-dipole forces: A polar molecule is one in which there is a permanent dipole, arising usually because the different atoms in the molecule have different electro-negativities. Hydrogen chloride is a polar molecule as the pair of electrons in the H---Cl bond are nearer the Cl atom because it has a greater electronegativity than the H atom. The two electrons of the covalent bond between the hydrogen and chlorine atoms are nearer the chlorine atom because of its greater electronegativity. Thus there will be an attraction between the chlorine atom of one molecule and the hydrogen atom of a neighbouring molecule. Hydrogen bonds: The second type of intermolecular force is the hydrogen bond. The permanent dipole in a covalent bond between a hydrogen atom and a fluorine, oxygen or nitrogen atom is particularly strong. Thus the attraction between the electron deficient H of one molecule and the lone pair of electrons on a fluorine, oxygen or nitrogen atom of another molecule is much stronger than the permanent dipole-dipole attraction between the two hydrogen chloride molecules. This particular type of dipole-dipole attraction between the electron deficient H of one molecule and the lone pair of electrons on a fluorine, oxygen or nitrogen atom of another molecule is given the special name of hydrogen bond. Even though a hydrogen bond has only about 5% the strength of a covalent bond, it does have significant effects on the physical properties of compounds. Were it not for hydrogen bonds both water and alcohol would be gases at room temperature and pressure. Hydrogen bonds explain the lower volatility of alcohols compared to that of alkanes of similar molecular mass. van der Waals’ forces: van der Waals’ forces are induced dipole-dipole interactions. They arise out of movement of the electrons in the shells.These induced dipole-dipole interactions, called van der Waals’ forces occur in all molecules, whether polar or not, but are the only intermolecular forces between non-polar molecules such as the halogens and the noble gases. As the number of electrons in the molecule increases, so do the van der Waals’ forces. SUBSCRIBE to the Fuse School YouTube channel for many more educational videos.

Types of Bond: Ionic, Covalent, Coordinate, and Hydrogen Bonds
 
02:42
Types of Bond in chemistry are explained in this video. The explanation of chemical bonding and different types of chemical bonds that are explained in this video include ionic bonds, covalent bonds, coordinate bonds, and hydrogen bonds. Ionic Bond: Ionic bonding is seen when two atoms form a bond by donating or accepting electrons. In this type of chemical bonding, there is an electrostatic attraction between the ions which are oppositely charged. Covalent Bond: In covalent bonding, two atoms share electrons to be able to attain the configuration of their nearest noble gas. It is also called a molecular bond and is characterized by electrons sharing between atoms. Coordinate bond: In the case of coordinate bonding, both the electrons that form the bond come from the same atom. Coordinate bond is also known as a coordinate covalent bond or a dative covalent bond. Hydrogen Bond: Hydrogen bonding is a type of electrostatic attraction and is seen when a hydrogen atom which is bonded to a highly electronegative atom (like Nitrogen, Oxygen, Fluorine) comes close to another adjacent atom having a lone pair of electrons.

Hydrogen Bonding---(হাইড্রোজেন বন্ধন)(Speaking in Bangla)
 
16:40
Hydrogen Bonding (হাইড্রোজেন বন্ধন) A hydrogen bond is a weak type of force that forms a special type of dipole-dipole attraction which occurs when a hydrogen atom bonded to a strongly electronegative atom exists in the vicinity of another electronegative atom with a lone pair of electrons. These bonds are generally stronger than ordinary dipole-dipole and dispersion forces, but weaker than true covalent and ionic bonds. _ Fair Use Disclaimer: This channel may use some copyrighted materials without specific authorization of the owner but contents used here falls under the “Fair Use” as described in The Copyright Act 2000 Law No. 28 of the year 2000 of Bangladesh under Chapter 6, Section 36 and Chapter 13 Section 72.

Covalent Bonding in Water, Methane, Ammonia & Hydrogen Fluoride | Chemistry for All | FuseSchool
 
05:16
In this video we will look at covalent bonds in methane, ammonia, water and hydrogen fluoride. They are small, covalently-bonded molecules. The atoms within them share electrons because they have half full or more than half full valence shells of electrons: they are non-metals. Methane is a fuel, ammonia is used in household cleaners, water is a drink and the essence of life, and hydrogen fluoride is used to etch glass. The bonding in methane, ammonia, water and hydrogen fluoride shows a pattern: methane is carbon bonded to four hydrogen atoms; ammonia is nitrogen bonded to three hydrogen atoms; water is oxygen bonded to two hydrogen atoms, and hydrogen fluoride is fluorine bonded to just one hydrogen atom. Carbon, nitrogen, oxygen and fluorine appear in the periodic table in this order, moving along the second row from left to right. Carbon has four out of eight electrons in its outer shell, so makes four covalent bonds. Nitrogen has five out of eight electrons in its outer shell, so can make three covalent bonds to make the shell full. Oxygen has 6 electrons in its outer shell. It can bond with two hydrogen atoms to share 2 more electrons. It now has a full outer shell of 8 electrons. Ammonia has two electrons, called a lone pair of electrons, occupying the fourth position. These electrons take up space. Because electrons are negatively charged, lone pairs repel bonds even more strongly than bonds repel each other. This makes ammonia less symmetric than methane. The water molecule is bent in shape. Oxygen has two lone pairs. Negatively charged lone pairs are slightly attracted to the hydrogen atoms, so there is a weak attraction between molecules. Forces between molecules are a little stronger in water than in ammonia or methane. Water is liquid at room temperature and pressure, whilst ammonia a gas that is easily liquefied, and methane is a gas. Intermolecular forces are normally very weak in covalent compounds, but in water they are just strong enough to keep it liquid. A bit more energy is needed to overcome these forces and boil it. If water were not a liquid, life as we know it would be completely different! Ethanol contains carbon and oxygen bonding. The carbon atoms always form four bonds and the oxygen forms two. Remember, carbon forms 4 bonds, nitrogen forms 3 bonds and has one lone pair of electrons, and oxygen forms two bonds and looks bent.
