The correct order of increasing intermolecular hydrogen bond strength is

Options

  1. AHCN < H 2 O < NH 3
  2. BHCN < CH 4 < NH 3
  3. CCH 4 < HCN < NH 3
  4. DCH 4 < NH 3 < HCN

Correct answer

C. CH 4 < HCN < NH 3

Step-by-step solution

The strength of Inter molecular Hydrogen bond decreases in the following order Order of H-Bonding: CH 4 < HCN < NH 3 For stronger hydrogen bond the size of electronegative atoms should be small. The smaller the size of electronegative atoms, the greater is the attraction for the bonded electron pair. This causes greater polarity in the H and the electronegative atom, resulting in stronger intermolecular hydrogen bonding. NCH . . . NCH H 2 NH . . . NH 3 Methane doesn&#39;t form hydrogen bonds and H 2 O much stronger
