Question

What technique is used to separate chloroform from aniline?

• A. Fractional distillation
• B. Simple distillation
• C. Filtration
• D. Evaporation

Hint:

Fractional distillation is ideal for separating liquids with different boiling points, especially when they are close but not identical.

Answer 1

The Correct Option is A

The separation of chloroform from aniline can be efficiently done by fractional distillation due to the difference in their boiling points.

1. Step 1: Understand fractional distillation. - Fractional distillation is used to separate liquids with different boiling points. Chloroform and aniline have significantly different boiling points, making this method effective for their separation.

2. Step 2: Consider other options. - Simple distillation would not be as effective as fractional distillation for separating chloroform and aniline because the boiling points are not different enough. - Filtration and evaporation are not applicable methods for separating liquids. Thus, fractional distillation is the correct method.
