Definition of hydrogen bond in English:

hydrogen bond


  • A weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other.

    • ‘The two electronegative atoms involved in a hydrogen bond are not bonded covalently; they are non-covalent, electrostatic partners.’
    • ‘Each hydrogen bond between molecules is much weaker than the covalent bonds holding the atoms together within the molecule.’
    • ‘Compared to say, a covalent bond, a hydrogen bond is approximately one tenth of that strength.’
    • ‘This is consistent with a structure that has lost the intramolecular hydrogen bond.’
    • ‘Breaking a single hydrogen bond may impair the stability of a protein.’
