Question

hydrogen bonding in molecules of HF H2O and NH3

Answer 1

The trend of the strength of thehydrogen bonding of HF (10 KCal/mol) > H2O (7 KCal/mol) > NH3 (2 KCal/mol). Hoever, the extent ofHydrogen bonding is H2O > HF > NH3. ... Water molecule has twice as manyhydrogen atoms as does HF and, therefore, water can theoretically form more hydrogen bonds than hydrogenfluoride.
