What is the Hydrogen Bond?
The hydrogen bond is a type of attractive force that exists between a hydrogen atom in a molecule and an atom of another element. It is the strongest type of intermolecular force and is the main cause of the unique properties of water and other molecules. Hydrogen bonds are responsible for many of the physical properties of liquids, such as surface tension and boiling point, as well as many of the properties of proteins and DNA.
What Causes Hydrogen Bonding?
Hydrogen bonding occurs when the electron density of a hydrogen atom is unevenly distributed around it. This causes the hydrogen atom to be slightly positive on one side, and slightly negative on the other. This uneven charge then forms an attractive force to an atom of another element, such as oxygen or nitrogen, that is also slightly charged. This attraction then forms a hydrogen bond.
The Strength of Hydrogen Bonds
Hydrogen bonds are not as strong as covalent bonds, the bonds that hold atoms together in molecules. Instead, hydrogen bonds are weaker, but they can still have a major effect on the behavior of molecules. The strength of a hydrogen bond varies based on the type of atom involved, but typically ranges from 5-10 kcal/mol.
Types of Hydrogen Bonds
Hydrogen bonds can be classified in several different ways. One way is to classify them based on the type of molecule involved. Hydrogen bonds can exist between two molecules, such as in water, or between two atoms in a single molecule, such as in DNA. Another way to classify hydrogen bonds is based on the orientation of the atoms involved, such as linear or bent.
Examples of Hydrogen Bonds
Hydrogen bonds are responsible for many of the properties of water, such as its high boiling point and surface tension. They are also involved in many biological processes, such as the folding of proteins and the stability of DNA. Hydrogen bonds can also be found in many other molecules, such as methane and ammonia.
Conclusion:
Hydrogen bonding is a type of attractive force between a hydrogen atom and an atom of another element. It is the strongest type of intermolecular force and is responsible for many of the properties of liquids and proteins. Hydrogen bonds can be classified based on the type of molecule involved or on the orientation of the atoms involved. Examples of hydrogen bonding can be found in water, proteins, DNA, methane, and ammonia.
