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