Assertion A: A mixture contains benzoic acid and naphthalene. The pure benzoic acid can be separated out by the use of benzene.
Reason R: Benzoic acid is soluble in hot water.
The correct answer is option D: A is false, but R is true.
Explanation:
- The assertion states that the pure benzoic acid can be separated out from a mixture of benzoic acid and naphthalene by the use of benzene. However, this assertion is incorrect because benzene cannot be used to separate benzoic acid from the mixture.
- The reason states that benzoic acid is soluble in hot water, which is true. Benzoic acid is a polar compound, and it can form hydrogen bonds with water molecules. As a result, it dissolves in hot water more readily than in cold water.
- In order to separate benzoic acid from a mixture of benzoic acid and naphthalene, a suitable solvent should be chosen based on the differences in solubility of the two compounds. Since benzoic acid is soluble in hot water, it can be separated from naphthalene by dissolving the mixture in hot water and then cooling the solution. The benzoic acid will crystallize out, while the naphthalene will remain dissolved in the water.
- The use of benzene, as mentioned in the assertion, is incorrect. Benzene is a nonpolar solvent and does not have the ability to dissolve polar compounds like benzoic acid. Therefore, it cannot be used to separate benzoic acid from the mixture.
In conclusion, the reason R is true as benzoic acid is soluble in hot water, but the assertion A is false as the use of benzene cannot separate benzoic acid from the mixture. Therefore, option D is the correct answer.
Reason R: Benzoic acid is soluble in hot water.
The correct answer is option D: A is false, but R is true.

Benzoic acid and naphthalene can be effectively separated by crystallisation. Benzoic acid is soluble in hot water, whereas naphthalene is insoluble.
Hence, A is false, but R is true.
Hence, A is false, but R is true.
