Question

The above conversion can proceed throuought is

• A. carbocation intermediate
• B. transition state
• C. free radical intermediate
• D. carbanion intermediate

Answer 1

Answer: (A)

carbocation intermediate

When treated with $HBr$ or $HCl$ alcohols typically undergo nucleophilic substitution reaction to generate an alkyl halide and water. The reaction usually proceeds via a $S_{N}1$ mechanism which proceeds via carbocation intermediate that undergoes rearrangement cleavage of $C-O$ bond allows a carbocation intermediate. This is the rate-determining step.
