Question

Quizplus · Accepted Answer

The reaction is an SN1 reaction, where the leaving group (Br) leaves first to form a carbocation intermediate, which then reacts with the nucleophile (OH-) to form the final product. The carbocation intermediate is stabilized by resonance and can form two possible products, III and IV. However, since III is more stable due to the electron-donating effect of the tert-butyl group, it is the major product. Therefore, the best choice is C.
