JEE MainChemistryGeneral Organic Chemistry
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : Aniline is separated from an aniline-water mixture using steam distillation. Reason (R) : Aniline is completely miscible with water and boils at a temperature significantly higher than water. In the light of the above statements, choose the most appropriate answer from the options given below:
Options
- A(A) is true but (R) is false.
- BBoth (A) and (R) are true and (R) is the correct explanation of (A).
- CBoth (A) and (R) are true but (R) is not the correct explanation of (A).
- D(A) is false but (R) is true.
Correct answer
A. (A) is true but (R) is false.
Step-by-step solution
Assertion (A) is correct because steam distillation is the standard technique used to separate aniline from an aniline-water mixture. Reason (R) is incorrect because steam distillation is specifically employed for substances which are steam volatile and immiscible with water. Aniline is immiscible with water, not completely miscible. Therefore, (A) is true but (R) is false. Answer: (A) is true but (R) is false.
