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 thevapour phase is same as that of the liquid phase of azeotropic mixture.

Assertion : Azeotropic mixtures are formed only by non-ideal solutions

1.	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 thevapour phase is same as that of the liquid phase of azeotropic mixture.
Answer» If both assertion and reason are true and the reason is the correct explanation of the assertion. If both assertion and reason are true but reason is not the correct explanation of the assertion. If assertion is true but reason is false. If the assertion and reason both are false. Solution :Non-ideal solutions with positive deviation i.e., having more VAPOUR pressure than expected, BOIL at LOWER temperature while those with negative deviation boil at HIGHER temperature than those of the COMPONENTS.
