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

Options

A. A-B interactions are stronger than those between A-A or B-B.
B. vapour pressure of solution increases because more number of molecules of liquids A and B can escape from the solution.
C. vapour pressure of solution decreases because less n umber of molecules of only one of the liquids escape from the solu tion.
D. A-B interactions are weaker than those between A- AorB-B.

Answer

A

Explanation

If A-B interactions is less than A-A or B-B the vapour pressure will be more and the result will be positive deviation. The solutions which exhibits positive deviation form minimum boiling azeotropes
