The molecular weight of benzoic acid in ...

The molecular weight of benzoic acid in benzene as determined by depression in the freezing point method corresponds to

A

Ionization of benzoic acid

B

Dimerization of benzoic acid

C

Trimerization of benzoic acid

D

Solvation of benzoic acid

Text Solution

Verified by Experts

The correct Answer is:
B
Molecular weight of benzoic acid in benzene is determined by the depression in freezing point method. And comes out to be `244`. The actual molecules mass is `122`. Therefore, it corresponds to the dimers which are formed by hydrogen bonding.
