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 biological conditions. 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 to see some different kinds of hydrogen bonds. Importance. Hydrogen bonds are extremely important in biological systems. Thier presence explains many of the properties of water.
