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.

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.

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.

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.

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.

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?

Why do H2O Molecules form more Hydrogen Bonds compared to NH3 and HF Molecules
 
08:45
H2O molecules have two Hydrogens bonded to an extremely electronegative Oxygen. The H therefore has strong partial positive charge. The Oxygen on the other hamd has two spare lone pairs which have high charge density. So overall two lone pairs will attract two partial positive H. In NH3, Nitrogen has only one lone pair but three partial positive Hydrogen that are directly bonded to electronegative Nitrogen. Now 1 lone pair on N will only attract 1 partial positive H. 2 partial positive will then not be able to attract lone pairs as lone pairs are not available. so fewer hydrogen bonds will be formed. In HF, there is only 1 partial positive H but three lone pairs on Flourine. So again, two extra lone pairs will not be able to form Hydrogen bonds due to non availability of partial positive H, so few Hydrogen bonds will be formed in HF. Hence NH3 and HF will have lesser melting and boiling points compared to H2O.

Polar & Non-Polar Molecules: Crash Course Chemistry #23

*** PLEASE WATCH WITH ANNOTATIONS ON! SOME INACCURACIES IN GRAPHICS ARE NOTED AND CORRECTED IN ANNOTATIONS. THANKS! *** Molecules come in infinite varieties, so in order to help the complicated chemical world make a little more sense, we classify and categorize them. One of the most important of those classifications is whether a molecule is polar or non-polar, which describes a kind of symmetry - not just of the molecule, but of the charge. In this edition of Crash Course Chemistry, Hank comes out for Team Polar, and describes why these molecules are so interesting to him. You'll learn that molecules need to have both charge asymmetry and geometric asymmetry to be polar, and that charge asymmetry is caused by a difference in electronegativities. You'll also learn how to notate a dipole moment (or charge separation) of a molecule, the physical mechanism behind like dissolves like, and why water is so dang good at fostering life on Earth. -- Table of Contents Charge Assymetry & Geometric Asymmetry 01:33 Difference in Electronegatives 01:49 Hank is Team Polar 00:33 Dipole Moment 03:49 Charge Separation of a Molecule 04:12 Like Dissolves Like 04:41 Water is Awesome 05:10 -- Want to find Crash Course elsewhere on the internet?

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.

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.

Structure Of Water Molecule - Chemistry Of Water - Properties Of Water - Composition Of Water
 
02:13
In this video we discuss the structure of water. We cover how and why is water a solvent to other substances, and how the ability of water to act as a solvent makes it a great transporting agent in the body. Transcript and notes The structure of water The chemistry of water Water is an inorganic molecule that is the most important compound in the body. In fact, a normal adult’s body weight is made up of 50% or more of water. A molecule of water has one oxygen atom covalently bonded to 2 hydrogen atoms. Covalent bonds being chemical bonds that are formed by the sharing of one or more pairs of electrons by the outer energy levels or shells of two atoms. Water molecules are also polar molecules, even though the oxygen atom shares electrons with the hydrogen atoms, the electrons are not shared equally within the molecule. This gives the oxygen side of the molecule two partial negative charges, and each of the hydrogen’s a slightly positive charge. This means that each water molecule can form up to 4 hydrogen bonds with adjacent water molecules. Hydrogen bonds are the result of an unequal charge distribution on a molecule, these molecules are said to be polar. This property allows water to act as a very effective solvent, which means it is able to dissolve or break apart many other substances. Substances that do dissolve or break apart in water are called hydrophilic, which means water loving. Non polar substances that do not dissolve in water are called hydrophobic, or water fearing. Some substances such as glucose molecules dissolve and remain intact in water, as water molecules surround the substance forming a hydration shell around the molecule. Some substances dissolve and dissociate or break apart in water. Table salt or NaCl, when added to water will dissociate to form positive Na ions and negative Cl ions, with hydration shells forming around each ion. This property of water allows it to function as a transporter, as water based fluids such as blood transport substances dissolved in water throughout the body. Non polar hydrophobic substances such as fats and cholesterol that do not bond with water must be enclosed within a transport protein molecule to be transported within blood. Other notes Water also absorbs and gives up heat slowly, which means it retains a relatively constant temperature. This property plays an important role in maintaining body temperature. This can be seen during exercise, as water or sweat is evaporated from the surface of the skin. Water also functions as a lubricant moistening food making it easier to swallow and decreasing friction as is the case with synovial fluid located within certain joints. Water acts as a cushion in some areas of the body, as the fluid surrounding the brain and spinal cord are water based. Water helps keep tissues moist, such as the eyes, nose and throat, enabling them to function properly as well as helping keep skin from drying and cracking. And water helps to excrete wastes in the body, as some unwanted substances are eliminated through urine.

Hydrogen Bonding vs Dipole-Dipole vs Dispersion forces of attraction between molecules
 
06:43
This video focuses on 3 intermolecular forces of attraction, based upon how strong the forces of attraction are. Hydrogen bonding (not a bond, but named as such) is the strongest force of attraction, then dipole-dipole is the intermediate in strength force of attraction, and finally, the dispersion force is the weakest, because it is a temporary polarity (like making a paperclip magnetized). These 3 forces explain the trends in boiling points, and the anomolies found in those trends. The anomolies led to the "discovery" or the naming of the strongest force of attraction, the hydrogen bonding capability of polar molecules that involve H directly bonded to either F, N, or O.

Water has an important role in synthesising and breaking down biological molecules in condensation and hydrolysis reactions. Water is also a key reactant used in photosynthesis. Water also has many other essential roles for life due to its unique properties - these properties occur due to its structure. Chemical Structure of Water Water consists of 2 hydrogen atoms and 1 oxygen atom, giving it the molecular formula H2O. The hydrogen atoms are bonded to oxygen atoms through covalent bonds. Covalent bonds are formed when electrons are shared between two atoms in order to fill the outer shell. A covalent bond is one in which two atoms share the same pair of electrons. The Polar Nature of Water The electrons in the covalent bonds of water are not equally shared - they lie closer to the oxygen nucleus than the hydrogen nuclei. This is because the negative electrons are more attracted to the oxygen nucleus as there are more positively charged protons. The unequal sharing of the electrons result in the oxygen atom being slightly negative and the hydrogen atoms being slightly positive. The uneven distribution of charge across the water molecule makes it a polar molecule. Polar molecules are molecules that have an uneven distribution of charge. Hydrogen Bonding in Water The slightly positive hydrogen atoms in one water molecule are attracted to the slightly negative oxygen atom in another water molecule. This attraction is called a hydrogen bond and is weaker than a covalent bond but stronger than most intermolecular forces. A hydrogen bond is a weak interaction that occurs between a slightly negatively charged atom and a slightly positively charged atom. Although each individual hydrogen bond is weak, water forms many of these hydrogen bonds. The polar nature of water along with the formation of these hydrogen bonds give water many unique properties that are essential for life. Summary Water is an essential component of cells with major roles in metabolism, including condensation and hydrolysis reactions Water is composed of an oxygen atom joined to two hydrogen atoms with covalent bonds The negative electrons are more attracted to the oxygen atom than the hydrogen atoms This results in an uneven distribution of charge across the molecule, making it polar Hydrogen bonds occur between polar molecules like water as there is a weak attraction between slightly positive and slightly negative atoms The polar nature of water and the formation of hydrogen bonds give water many unique properties that are essential for life
