Hydrogen bond

Jump to: navigation, search


A type of chemical bond. A hydrogen bond is formed when a hydrogen atom in a molecule, such as water, is attracted to an electronegative element, such as F, N, or O, in another molecule. The hydrogen atom forms the positive end of a bridge, called a hydrogen bond, between itself and the other electronegative element. Hydrogen bonds are about one-tenth as strong as covalent bonds. They influence boiling points, melting points, and crystallinity of materials.
