STATEMENT - 1 : The molecular mass of acetic acid determined by depression in freezing point method in benzene and water was found to be differrent.
STATEMENT - 2 : Water is polar and benzene is non-polar.

A

If both assertion and reason are true, and reason is the true explanation of the assertion.

B

If both assertion and reason are true, but reason is not the true explanation of the assertion.

C

If assertion is true, but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

R is the correct explanation of A. (In water, benzoic acid undergoes dissociation while in benzene, it undergoes association).
