Hydrogen bond
A hydrogen bond is the electrostatic attraction between polar groups that occurs when a hydrogen (H) atom bound to a highly electronegative atom such as nitrogen (N), oxygen (O) or fluorine (F) experiences attraction to some other nearby highly electronegative atom.
These hydrogen-bond attractions can occur between molecules (intermolecular) or within different parts of a single molecule (intramolecular). Depending on geometry and environmental conditions, the hydrogen bond may be worth between 5 and 30 kJ/mole in thermodynamic terms. This makes it stronger than a van der Waals interaction, but weaker than covalent or ionic bonds. This type of bond can occur in inorganic molecules such as water and in organic molecules like DNA and proteins.
Intermolecular hydrogen bonding is responsible for the high boiling point of water (100 °C) compared to the other group 16 hydrides that have no hydrogen bonds. Intramolecular hydrogen bonding is partly responsible for the secondary and tertiary structures of proteins and nucleic acids. It also plays an important role in the structure of polymers, both synthetic and natural.

Hydrogen Bonds - What Are Hydrogen Bonds - How Do Hydrogen Bonds Form
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...

Hydrogen Bonding and Common Mistakes
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.

A Level Chemistry Revision "Hydrogen Bonding".
You can find all my A Level Chemistry videos fully indexed at https://www.freesciencelessons.co.uk/a-level-revision-videos/a-level-chemistry/ In this video, we finish looking at intermolecular forces by exploring Hydrogen bonding. First we look at what is meant by a Hydrogen bond and the correct way to draw them. We then look at the conditions needed to form a Hydrogen bond and why these only form with fluorine, oxygen or nitrogen. Finally, we look at Hydrogen bonding in water and see how Hydrogen bonding gives water its unusual properties. This video is aimed at the UK A Level Chemistry specifications. Students studying International A Level Chemistry will need to check their specification. Image credits: Iceberg https://commons.wikimedia.org/wiki/File:Iceberg_with_hole_near_Sanderso...

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.

-------------------------------------------------------
**What are Electric Charges?**
Electric charges are fundamental properties of matter that cause it to experience a force when placed in an electric field. Charges come in two types: positive and negative. Like charges repel each other, while opposite charges attract. This force between charges is a central concept in the study of electricity.
-------------------------------------------------------
**How Do Electric Charges Interact?**
The interaction between electric charges can be described by Coulomb's Law. This law states that the force between two charges is directly proportional to the product of their magnitudes and inversely proportional to the square of the distance between them. Essentially, the closer and larger the charges, the stronger the force between them.
Let's consider two charged particles. If both have the same type of charge, they will repel each other. If one has a positive charge and the other a negative charge, they will attract each other. This attraction or repulsion happens because charged particles create electric fields around them. These fields influence other charges within their reach.
-------------------------------------------------------
**Why Do Some Materials Conduct Electricity?**
Materials can be classified based on their ability to conduct electricity. Conductors, like metals, have free electrons that can move easily throughout the material, allowing electric charges to flow. Insulators, such as rubber or glass, do not have free electrons, so they resist the flow of electric charges.
For example, when you connect a battery to a copper wire, the free electrons in the wire start to move from the negative terminal towards the positive terminal, creating an electric current. On the other hand, if you try the same with a plastic rod, no current will flow because plastic does not have free-moving electrons.
-------------------------------------------------------
**Why Don’t All Materials Conduct Electricity?**
The ability of a material to conduct electricity depends on its atomic structure. Conductors have atoms with loosely bound outer electrons, making it easy for these electrons to move. Insulators have tightly bound electrons that are not free to move.
In some materials, like semiconductors, the conductivity can change under certain conditions, such as exposure to light or heat. This unique property makes semiconductors vital in modern electronics, like computers and smartphones.
-------------------------------------------------------
**Electric Charge and Everyday Life**
Understanding electric charges helps explain everyday phenomena. For instance, when you rub a balloon on your hair, electrons transfer from your hair to the balloon, making your hair positively charged and the balloon negatively charged. This opposite charge causes your hair to stick to the balloon.
-------------------------------------------------------
**Conclusion**
Electric charges are a fundamental aspect of physics that explain many natural and technological phenomena. Conductors, insulators, and the forces between charges all play a crucial role in our understanding and use of electricity.

The interaction between electric charges can be described by Coulomb's Law. This law states that the force between two charges is directly proportional to the product of their magnitudes and inversely proportional to the square of the distance between them. Essentially, the closer and larger the charges, the stronger the force between them.
Let's consider two charged particles. If both have the same type of charge, they will repel each other. If one has a positive charge and the other a negative charge, they will attract each other. This attraction or repulsion happens because charged particles create electric fields around them. These fields influence other charges within their reach.
-------------------------------------------------------
**Why Do Some Materials Conduct Electricity?**
Materials can be classified based on their ability to conduct electricity. Conductors, like metals, have free electrons that can move easily throughout the material, allowing electric charges to flow. Insulators, such as rubber or glass, do not have free electrons, so they resist the flow of electric charges.
For example, when you connect a battery to a copper wire, the free electrons in the wire start to move from the negative terminal towards the positive terminal, creating an electric current. On the other hand, if you try the same with a plastic rod, no current will flow because plastic does not have free-moving electrons.
-------------------------------------------------------
**Why Don’t All Materials Conduct Electricity?**
The ability of a material to conduct electricity depends on its atomic structure. Conductors have atoms with loosely bound outer electrons, making it easy for these electrons to move. Insulators have tightly bound electrons that are not free to move.
In some materials, like semiconductors, the conductivity can change under certain conditions, such as exposure to light or heat. This unique property makes semiconductors vital in modern electronics, like computers and smartphones.
-------------------------------------------------------
**Electric Charge and Everyday Life**
Understanding electric charges helps explain everyday phenomena. For instance, when you rub a balloon on your hair, electrons transfer from your hair to the balloon, making your hair positively charged and the balloon negatively charged. This opposite charge causes your hair to stick to the balloon.
-------------------------------------------------------
**Conclusion**
Electric charges are a fundamental aspect of physics that explain many natural and technological phenomena. Conductors, insulators, and the forces between charges all play a crucial role in our understanding and use of electricity.

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.

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.

**What are Electric Charges?**
Electric charges are fundamental properties of matter that cause it to experience a force when placed in an electric field. Charges come in two types: positive and negative. Like charges repel each other, while opposite charges attract. This force between charges is a central concept in the study of electricity.
-------------------------------------------------------
**How Do Electric Charges Interact?**
The interaction between electric charges can be described by Coulomb's Law. This law states that the force between two charges is directly proportional to the product of their magnitudes and inversely proportional to the square of the distance between them. Essentially, the closer and larger the charges, the stronger the force between them.

Hydrogen bond
A hydrogen bond is the electrostatic attraction between polar groups that occurs when a hydrogen (H) atom bound to a highly electronegative atom such as nitrogen (N), oxygen (O) or fluorine (F) experiences attraction to some other nearby highly electronegative atom.
These hydrogen-bond attractions can occur between molecules (intermolecular) or within different parts of a single molecule (intramolecular). Depending on geometry and environmental conditions, the hydrogen bond may be worth between 5 and 30 kJ/mole in thermodynamic terms. This makes it stronger than a van der Waals interaction, but weaker than covalent or ionic bonds. This type of bond can occur in inorganic molecules such as water and in organic molecules like DNA and proteins.
Intermolecular hydrogen bonding is responsible for the high boiling point of water (100 °C) compared to the other group 16 hydrides that have no hydrogen bonds. Intramolecular hydrogen bonding is partly responsible for the secondary and tertiary structures of proteins and nucleic acids. It also plays an important role in the structure of polymers, both synthetic and natural.
