An azeotropic mixture of chloroform and diethyl ether possesses boiling point higher than either that of chloroform or diethyl ether. The mixture shows

Options

A. negative deviation from Raoult's law
B. positive deviation from Raoult's law
C. no deviation from ideal behaviour
D. that the solution is saturated.

Answer

A

Explanation

Azeotropic mixtures with higher boiling point show negative deviation. There occurs H-bonding between chloroform and diethyl ether in the solution, hence the escaping tendency of either component becomes less.
