Benzene carbaldehyde is reacted with concentrated NaOH solution to give the products A and B. The product A can be used food preservative and the product B is an aromatic hydroxy compound where OH group is linked to `sp^3` hybridised carbon atom next to Benzene ring. The products A and B are respectively,

A

Sodium benzoate and phenol

B

sodium benzoate and phenyl methanol

C

sodium benzoate and cresol

D

sodium benzoate and picric acid.

Text Solution

Verified by Experts
