319420 If two liquids A and B form minimum boiling azeotrope at some specific composition then

1 A - B interactions are stronger than those between A - A or B - B
2 Vapour pressure of solution increases because more number of molecules of liquids A and B can escape from the solution
3 Vapour pressure of solution decreases because less number of molecules of only one of the liquids escape from the solution
4 A - B interactions are weaker than those between A - A or B - B

319421 Assertion :
An azeotropic solution of two liquids may have boiling point lower than either of them.
Reason :
Given solution shows +ve deviation from ideal behaviour.

1 If both Assertion & Reason are true and reason is the correct explanation of the assertion.
2 If both Assertion & Reason are true but reason is not the correct explanation of the assertion.
3 If Assertion is true but Reason is false.
4 If Assertion is false but Reason is true.

319422 Statement A :
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.
Statement B :
The composition of the vapour phase is same as that of the liquid phase of an azeotropic mixture.

1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both Statements are correct.
4 Both Statements are incorrect.
