Question

Quizplus · Accepted Answer

The reaction involves the addition of hydrogen bromide to an alkene. This is an example of electrophilic addition, where the HBr adds across the double bond, forming a carbocation intermediate. The bromide ion then acts as a nucleophile, attacking the carbocation and forming a new C-Br bond. In this case, the carbocation intermediate can undergo rearrangement to form a more stable tertiary carbocation. The major product of the reaction will be the one that comes from the most stable carbocation intermediate, which in this case is II.
