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 number of moleatles of only one of the liquids escape from the solution
D. A-B interactions are weaker than those between A-A or B-B.

Answer

D

Explanation

When solute - solvent or A-B interactions are weaker than the A-A or B-B interactions molecules of A or B will find it easier to escape than in pure state .this will increase the vapour pressure and result in positive deviation from Raoult.s law .such solutions are called minimum boilin azeotropes.
