Identify the product A in the given reaction,

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
A
Tautomerization of trihydric phenol (I) gives triketone (II). Abstraction of a proton by the base `OH^(-)` gives a stable carbanion (III) which reacts with Me-I by `S_(N)2` mechanism to give product (IV). Repeated abstraction of a proton followed by `S_(N)2` mechanism with MeI gives the final product (V).
