Question

Quizplus · Accepted Answer

The reactive intermediate in the reaction of 1,3-diene with HBr, resulting in 1,4-addition, is an allylic carbocation. This intermediate is formed when the diene reacts with HBr, and the initial protonation occurs at one end of the diene, leading to a more stable allylic carbocation, which then reacts further to complete the addition.
