Properties of hydrogen bonds.
- How are they formed? a hydrogen bond is formed when a charged
part of a molecule having polar covalent bonds forms an electrostatic (charge,
as in positive attracted to negative) interaction with a substance of opposite
charge. Molecules that have nonpolar covalent bonds
donot form hydrogen bonds.
- Strenght. Hydrogen bonds are classified as weak
bonds because they are easily and rapidly formed and broken under normal
- What classes of compounds can form hydrogen bonds? Under the
right environmental conditions, any compound that has
polar covalent bonds can form hydrogen bonds. Click here

- Importance. Hydrogen bonds are extremely important in biological
systems. Thier presence explains many of the properties of water.
They are used to stabilize and determine the structure of large macormolecules
like proteins and nucleic acids. They are involved in the mechanism of
