उत्तर
The molecular weight of benzoic acid in benzene as determined by depression of freezing point method corresponds to dimerisation of benzoic acid.
Explanation:
In non-polar solvents like benzene, benzoic acid tends to dimerise due to hydrogen bonding. This reduces the number of solute particles in solution, leading to a higher observed molecular weight, as seen in freezing point depression experiments.
