Easy MCQ +4 / -1 PYQ · JEE Mains 2022

The correct order of increasing intermolecular hydrogen bond strength is :

  1. A HCN < H<sub>2</sub>O < NH<sub>3</sub>
  2. B HCN < CH<sub>4</sub> < NH<sub>3</sub>
  3. C CH<sub>4</sub> < HCN < NH<sub>3</sub> Correct answer
  4. D CH<sub>4</sub> < NH<sub>3</sub> < HCN

Solution

Due to the high difference in electronegativity of H and N the H-bond strength of NH<sub>3</sub> is highest. There is no H-bond in CH<sub>4</sub>.<br/><br/> CH<sub>4</sub> < HCN < NH<sub>3</sub>
