Hydrogen bonding effectMediumQuestion 600332

Question

HF has a higher boiling point than HCl because:
  1. A
    HF has higher molar mass
  2. B
    HF has stronger intermolecular H-bonding
    Correct
  3. C
    HF is more ionic
  4. D
    HF has weaker London forces

Correct answer

HF has stronger intermolecular H-bonding

Explanation

F is the most electronegative element → H−F bonds are highly polar → strong intermolecular H-bonding in HF. HCl has no significant H-bonding. Hence HF has an anomalously high boiling point.
