MCQ

Ethylene has high b.p. and high vapour pressure at ${100\,^o}C$ and does not dissolve in water. Hence ethylene is separated by this method

A
Simple distillation
B
Vacuum distillation
✓
Vapour distillation
D
Alkali treatment

✓

Answer

Correct option: C.

Vapour distillation

c
Steam Distillation also know as vapour Distillation:- This technique is used for separating substances which are immiscible with water, volatile in steam and having high vapour pressure at the boiling temperature of water. It is also used for purifying liquids which decompose at their normal boiling points.

Therefore, Ethylene has high $b.p.$ and high vapour pressure at $100^{\circ} C$ and does not dissolve in water. Hence, ethylene is separated by thi vapour distillation method.
