Vedclass · Accepted Answer

If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.

Vedclass · Answer

(A) Colligative properties depend on the number of particles in the solution.Benzoic acid $(C_6H_5COOH)$ undergoes dimerisation in non-polar solvents like benzene due to hydrogen bonding.This process reduces the total number of particles in the solution.Since the colligative property is inversely proportional to the molar mass,a decrease in the number of particles leads to an abnormally high observed molecular mass compared to the theoretical value.

Assertion : Molecular mass of benzoic acid when determined by colligative properties is found high.
Reason : Dimerisation of benzoic acid.
