Which is the major product of the following reaction?

Question

Quizplus · Accepted Answer

The reaction starts with the addition of hydrogen bromide (HBr) across the double bond, forming a carbocation intermediate. The carbocation can rearrange itself to a more stable structure through a hydride shift, where a hydrogen atom moves from the carbon next to the positive charge to the carbon with the positive charge. This results in the formation of a more stable tertiary carbocation. Next, the bromide ion attacks the carbocation, leading to the major product, which is the tertiary bromide (I). The other products (II, III, and IV) are possible minor products that could result from different mechanisms or pathways.
