Question

Arrange NH₃, H₂O and HF in the order of increasing magnitude of hydrogen bonding and explain the basis for your arrangement.

Answer 1

• The increasing magnitude of hydrogen bonding among NH₃, H₂O, and HF is HF > H₂O > NH₃
• The extent of hydrogen bonding depends upon electronegativity and the number of hydrogen atoms available for bonding.
• Among N, F, and O the increasing order of their electronegativities are N < O, H₂O > NH₃.
