The reaction involves the reaction of tert-butyl bromide with sodium iodide in acetone. This reaction is an example of a nucleophilic substitution reaction, specifically a SN1 reaction. The mechanism involves the formation of a carbocation intermediate, which can then react with the nucleophile (iodide ion) to give the product.
The major products of the reaction are therefore the result of the nucleophilic attack of iodide ion on the carbocation intermediate. The primary carbocation intermediate formed is III, which can react with the iodide ion to give product IV. The secondary carbocation intermediate formed is I, which can react with iodide ion to give product I. Therefore, the major products are I and IV, which are obtained in good yield. Choice D is the best answer.
