Question

Assertion : Azeotropic mixtures are formed only by non - ideal solutions and they may have boiling points either greater than both the components or less than both the components.
Reason : The composition of the vapour phase is same as that of the liquid phase of an azeotropic mixture.

• A. Both assertion and reason are correct and the reason is a correct explanation of the assertion
• B. Both assertion and reason are correct but reason is not a correct explanation of the assertion
• C. The assertion is correct but reason is incorrect
• D. Both assertion and reason are incorrect

Answer 1

The correct option is B Both assertion and reason are correct but reason is not a correct explanation of the assertion

Azeotropic mixtures are formed only by non - ideal solutions and they may have boiling points either greater than both the components or less than both the components and based on that they are called maximum boiling azeotrope and minimum boiling azeotrope respectively.
Azetropic mixtures are binary mixtures having the same composition in liquid and vapour phase and boil at a constant temperature.
