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.

Properties of Water | Hydrogen Bonding in Water | Biology | Biochemistry
 
12:37
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. Also appropriate for advanced homeschoolers. You can also follow along if you are just curious, and would like to know more about this fascinating subject.

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?

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.

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.

Chemical Bonds In The Body - Types Of Chemical Bonds - What Are Ionic Bonds And Covalent Bonds
 
04:18
In this video we discuss how chemical bonds are formed, we cover ionic bonds and covalent bonds. Chemical bonding is important in many different functions of the body. Transcript and notes The interactions of 2 or more atoms mainly occur at the outermost shell, or energy level. The result of these interactions results in a chemical reaction. In atoms that have fewer or more than 8 electrons in their outermost energy level, reactions occur that result in the loss, gain, or sharing of electrons with another atom to satisfy the octet rule. The octet rule means that elements tend to combine so that each atom has 8 electrons in its outermost shell. This results in the formation of structures such as crystals or molecules. Two atoms of oxygen can combine with one atom of carbon to form carbon dioxide or CO2. There are two main types of chemical bonds, ionic bonds and covalent bonds. Ionic bonds are bonds where the transfer of electrons takes place. Let’s see how this type of bond works. So, here we have a sodium atom, which has an atomic number of 11, meaning it has 11 protons in its nucleus and 11 electrons in its shells or energy levels. Shell one has 2 electrons, shell 2 has 8 electrons and shell 3 has 1 electron. And here we have a chlorine atom, which has an atomic number of 17, so 17 protons and 17 electrons. It has 2 electrons in shell one, 8 in shell 2 and 7 in shell 3. We know that atoms want to have 8 electrons in their outer shell, so Sodium can give up one electron, and now it has 8 electrons in its outer shell, and chlorine can take that electron from sodium and that will give it 8 electrons in its outer shell. Since the sodium atom gave up an electron it now has 11 protons, which are positively charged, and 10 electrons which are negatively charged. This results in the formation of a sodium ion with a positive charge. An ion is an atom or molecule with a net electrical charge due to the loss or gain of an electron. Since the chlorine atom gained an electron, and now has 17 protons and 18 electrons, it is a chlorine ion with a negative charge. The positively charged sodium ion is now attracted to the negatively charged chlorine ion, and NaCl or table salt is formed. This is an ionic bond. So, ionic bonding is when an electron transfer takes place and generates 2 oppositely charged ions. Now for covalent bonds. Covalent bonds are 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. The 4 major elements of the body, carbon, oxygen, hydrogen and nitrogen almost always form covalent bonds by sharing electrons. So, for instance, 2 hydrogen atoms can bond by sharing a pair of electrons. Hydrogen is one of the exceptions to the octet rule of having 8 electrons in the outer shell, because it only has one shell. Let’s look at carbon dioxide or co2 again, which form a covalent bond. Oxygen has an atomic mass of 8, so 8 protons, and 8 electrons, 2 in its inner shell and 6 in its outer shell, so, oxygen atoms want 2 more electrons for their outer shell. Carbon has an atomic mass of 6, 6 protons and 6 electrons, 2 in the inner shell and 4 in the outer shell, so it wants 4 more electrons for its outer shell. They can make each other happy by sharing what they have. Oxygen atom number 1 can share 2 of its electrons and the carbon atom can share 2 of its electrons with oxygen atom number one, making oxygen atom number one happy. And oxygen atom number 2 can come in and like oxygen atom number one it can share two of its electrons and the carbon atom has 2 more of its own electrons that it can share with oxygen atom number 2. So now all 3 atoms are happy. By sharing 2 pairs of electrons in this situation a double bond has been formed, and double bonds are important in chemical reactions.

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: A Polar Molecule
 
08:37
Water: A Polar Molecule In this video Paul Andersen explains how the polarity of water makes life on the planet possible. Oxygen is highly electronegative and pulls the electrons closely creating a partial negative charge. The polarity of water (and the corresponding hydrogen bonds) create cohesion, adhesion, capillary action, high specific heat, and a universally good solvent. Do you speak another language?
