Question

Fractional distillation is used to obtain the components of which of the following?
I air
II seawater
III muddy water
IV crude oil

• A. I, II
• B. II, III
• C. I, IV
• D. I, III

Answer 1

Answer: (C)

I, IV

Fraction distillation is based upon the separation of components having very less boiling point difference, therefore components of crude oil and air can be separated using fractional distillation. In the air and in crude oil, the difference in boiling point of different components is very less.
