Question

Quizplus · Accepted Answer

The reaction involves an Sn1 mechanism in which the leaving group (Br) departs first, creating a primary carbocation that then undergoes a hydride shift to form a more stable secondary carbocation. The nucleophilic water attacks the carbocation to form the alcohol product. The structure of the major product is the one in which the hydroxy group is attached to the secondary carbon atom (i.e. the one in which the hydride shift took place), as this gives the more stable carbocation intermediate. This is shown in choice C.
