Affinity for hydrogen decreases in the group from fluorine to iodine. Which of the halogen acids should have highest bond dissociation enthalpy?

Options

  1. AHF
  2. BHCl
  3. CHBr
  4. DHI

Correct answer

A. HF

Step-by-step solution

F being smallest has the shortest HF bond and hence HF has the highest bond dissociation energy.
