What is the major product of the reaction,

Question

Quizplus · Accepted Answer

The reaction involves the addition of HBr across the double bond in the starting material. This results in the formation of a bromoalkane and a carbocation intermediate. The carbocation can then undergo a hydride shift to form a more stable carbocation, followed by attack by the bromide ion to form the final product. In this case, the hydride shift occurs from the carbon atom bearing the methyl group to the adjacent carbon atom, resulting in the formation of a more stable tertiary carbocation. The bromide ion then attacks at the carbon atom bearing the double bond, forming a new carbon-bromine bond and resulting in the formation of the product shown in option B.
