A weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other.
〔化〕氢键
Example sentencesExamples
The two electronegative atoms involved in a hydrogen bond are not bonded covalently; they are non-covalent, electrostatic partners.
Compared to say, a covalent bond, a hydrogen bond is approximately one tenth of that strength.
Each hydrogen bond between molecules is much weaker than the covalent bonds holding the atoms together within the molecule.
Breaking a single hydrogen bond may impair the stability of a protein.
This is consistent with a structure that has lost the intramolecular hydrogen bond.
