Predict the product for the following reaction.

Question

Quizplus · Accepted Answer

The reactants are a tertiary alcohol and a strong acid (HBr). This suggests that an elimination reaction (like E1 or E2) may occur. The strong acid protonates the alcohol, leading to the formation of a carbocation intermediate. The carbocation in this case is tertiary, making it relatively stable. The bromide ion can then act as a nucleophile and attack the carbocation, forming the final product II. The other potential products (I, III, and IV) involve different positions of the double bond and different stereochemistry, but are less likely to form due to steric hindrance or unfavorable energetics.
