As benzoic acid dimerises so number of moles decreases so osmotic pressure of benzoic acid is less than benzene.

Explanation:
Benzoic acid in benzene:
- Benzoic acid molecules can form associations in benzene due to the presence of hydrogen bonding.
- This association reduces the number of freely moving particles in the solution, leading to a decrease in osmotic pressure.
Association of benzoic acid:
- Benzoic acid molecules can undergo association through hydrogen bonding in benzene, forming dimers or higher aggregates.
- These associations reduce the effective concentration of benzoic acid particles in the solution, resulting in lower osmotic pressure than expected.
Impact on osmotic pressure:
- The reduced number of freely moving particles due to association results in a lower osmotic pressure compared to what would be expected based on the concentration of benzoic acid.
- This phenomenon is particularly significant in non-polar solvents like benzene, where the tendency for association through hydrogen bonding is high.
Conclusion:
- The decreased osmotic pressure of a solution of benzoic acid in benzene can be attributed to the association of benzoic acid molecules in the solvent, which reduces the effective concentration of solute particles and limits their mobility.
