Question

If the boiling point difference between the two liquids is not much, the ____ method is used to separate them.

• A. Simple distillation
• B. Distillation under reduced pressure
• C. Steam distillation
• D. Fractional distillation

Answer 1

The correct option is D Fractional distillation

Fractional distillation method is used if difference in boiling points of two liquids is not much and simple distillation can't be used to separate them. Hence, the correct answer will be option (d).
