Question

Given below are two statements:

Statement I: A mixture of chloroform and aniline can be separated by simple distillation.

Statement II: When separating aniline from a mixture of aniline and water by steam distillation aniline boils below its boiling point.

In the light of the above statements, choose the most appropriate answer from the options given below:

• A. Statement I is true and Statement II is false
• B. Both Statement I and Statement II are false
• C. Statement I is false and Statement II is true
• D. Both Statement I and Statement II are true

Answer 1

The correct option is D Both Statement I and Statement II are true

Mixture of chloroform and aniline can be separated by simple distillation as these two liquids have sufficient difference in boiling point: Chloroform (b.p. $334K$), aniline (b.p. $457K$).

In steam distillation, if one of the substances is water and the other, a water insoluble substance (like aniline) then the mixture will boil close to but below $373K.$
