Question

Alcohols can be prepared from alkenes using several distinct methods. Which of the following methods proceed explicitly via a classical carbocation intermediate and are therefore prone to structural rearrangements?

Prashant Kotian · Accepted Answer

Correct answer: A,D. Acid-catalyzed hydration (with dilute ) and standard hydrohalogenation (with ) both involve classical carbocation intermediates, which can rearrange to form more stable tertiary structures. Hydroboration and oxymercuration specifically avoid free classical carbocations to prevent rearrangements.
