MHT CET Chemistry Question (2026) — Solution

Step-by-step solution

The formation of alcohol from an alkene typically proceeds via acid-catalyzed hydration, which is an electrophilic addition reaction. The rate-determining step in this reaction is the attack of the electrophile (H^+) on the alkene to form a carbocation intermediate. The rate of the reaction is directly proportional to the stability of the carbocation formed. The stability of carbocations follows the order: 3^ > 2^ > 1^ due to the +I effect of alkyl groups and hyperconjugation. Therefore, the order of reactivity of alkenes towards hydration, and hence the rate of formation of alcohol, is 3^ > 2^ > 1^ . Answer: 3^ > 2^ > 1^
