A

In drying of alcohols

B

In drying of benzene

C

In drying of ammonia solution

D

Text Solution

Verified by Experts

The correct Answer is:
B
Moisture present in benzene reacts with Na to give NaOH and `H_(2)`. Distillation of the resulting solution gives dry benzene leaving NaOH in the flask.
Na metal cannot be used in drying of alcohols and ammonia solution because it reacts with these compounds.
