Draw the transition state for the following reaction.

Question

Quizplus · Accepted Answer

The transition state involves both the breaking of the C-I bond and the formation of the C-O bond. Based on the molecular orbitals of the reactants and product, it is likely that the reaction proceeds through a partial formation of the C-O bond before the full breaking of the C-I bond. This means that the transition state would have a partially formed C-O bond and a partially broken C-I bond, which is shown in option II.
