Question

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

Tardigrade Admin · Accepted Answer

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.

Cl - C ∣ l C ∣ C l - H - - - - - O <_{C_{2} H_{5}}^{C_{2} H_{5}}

positive deviation from Raoult’s law

no deviation from ideal behaviour

that the solution is saturated.

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. Cl−C∣lC∣C​l​−H−−−−−O<C2​H5​C2​H5​​
