A chemical relationship by which a hydrogen atom of just one molecule is attracted to an electronegative atom, specially a nitrogen, air, or flourine atom, generally of another molecule.
A weak relationship in which a hydrogen atom in one molecule is attracted to an electronegative atom (usually nitrogen or oxygen) in identical or different molecule.
a non-covalent bond between hydrogen and another atom, usually air or nitrogen. It does not include the sharing of electrons amongst the fused atoms, and as a consequence cannot match the valence of either atom. Hydrogen bonds tend to be poor (ca. 5 kcal/mol) and may be often damaged and reformed in solution at room-temperature.
a chemical bond comprising a hydrogen atom between two electronegative atoms (age.g., air or nitrogen) with one part be a covalent bond together with other being an ionic bond
