JEE Main · 2022 · 25 Jun 2022 · Shift 1 · Alcohols Phenols and Ethers

In the following reaction :

The compounds A and B respectively are :-

(A)(see structure), $CH_{3} COOH$
(B)(see structure), $CH_{3} COOH$
(C)(see structure), $CH_{3} COCH_{3}$
✓ Correct
(D)(see structure)

Answer: (C)

Solution

This is the cumene-peroxide method for the preparation of phenol. Cumene (isopropylbenzene) is oxidized to cumene hydroperoxide, which then undergoes acid-catalyzed cleavage to give phenol (A) and acetone (B). The correct answer is (C): phenol and CH₃COCH₃.
