Answer 1

An Azeotropic mixture of chloroform and diethyl ether possess boiling point higher than either that of chloroform or diethyl ether. The mixture shows that -

• It shows that the solution shows negative deviation from raoult's law.

• Means , the intermolecular forces present are strong than that of present in the ideal solution.

• if intermolecular forces are strong means total vapour pressure of the solution will be less than that of total vapour pressure of ideal solution . Also , the. vapour pressure of each component will be less than that predicted from raoult's law .

• As , vapour pressure and boiling point have inverse relation so we can say that boiling point of mixture of chloroform and diethyl ether will be more than either of them.

• Hence, Azeotropic mixture of chloroform and diethyl ether possess boiling point higher than that of chloroform or diethyl ether.
