Predict the product for the following reaction.

Question

Quizplus · Accepted Answer

The reactant is an alkene, and the product is formed by adding HBr across the double bond in a Markovnikov fashion. The bromine atom will attach to the more substituted carbon, resulting in the formation of a tertiary carbocation. The bromide ion will then attack the carbocation to give the final product, which is a tertiary alkyl bromide. Option IV is incorrect because it shows the opposite addition, which is anti-Markovnikov. Options I and II don't show tertiary carbocation formation.
