Question

Phenol on treatment with $C{O}_2$ in the presence of $NaOH$ fallowed by acidification produces compound $X$ as the major product. $X$ on treatment with $(C{H}_{3}CO{)}_{2}O$ in the presence of catalytic amount of $H_{2}S{O}_4$ produces:

• A.
• B.
• C.
• D.

Answer 1

The correct option is A


The very first reaction in the above road map looks like Kolbe's reaction which results to salicylic acid.
