Find the order of formation of alcohol from alkene from the following.
Options
- A3^ > 1^ > 2^
- B3^ > 2^ > 1^
- C1^ > 2^ > 3^
- D1^ > 3^ > 2^
Correct answer
B. 3^ > 2^ > 1^
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 o
