Hydrogen Bond — Chemistry Definition | AllChemicals | AllChemicals

What is Hydrogen Bond?

A hydrogen bond is a weak electrostatic attraction between a hydrogen atom covalently bonded to a highly electronegative atom (N, O, or F) and a lone pair on another electronegative atom nearby. Though individually weak (5–30 kJ/mol), hydrogen bonds collectively give water its anomalously high boiling point, surface tension, and ability to dissolve polar substances. They are also critical in stabilising DNA and protein structures.
