Which of the following concepts should be used to correctly describe the reason for enhanced regioselectivity of photobromination versus photochlorination?

Question

Quizplus · Accepted Answer

The Hammond postulate explains the enhanced regioselectivity of photobromination versus photochlorination by suggesting that the transition state of the reaction resembles the reactants or products depending on whether the reaction is endothermic or exothermic. In photobromination, the transition state is closer in energy to the reactants, leading to a more selective reaction.
