Absolute alcohol cannot be obtained by simple fractional distillation because

A

pure `C_2H_5OH` is unstable

B

`C_2H_5OH` forms hydrogen bonds with water

C

boiling point of `C_2H_5OH` is very close to that of water

D

constant boiling azeotropic mixture is formed with water

Text Solution

Verified by Experts

The correct Answer is:
D
The components of an azeotropic mixture are separated by special method, i.e., azeotropic distillation. The simple fraction which distils at 337.8K is a ternary azeotrope consisting of water, some alcohol and benzene.
