If two liquids A and B form minimum boiling azetrope at some spectific composition, then
A. A-B ineractions are stronger than those between A-A of B-B interactions.
B. Vapour pressure of solution increases because more mumber of molecules of liquids A and B can escape from the solution.
C. vapour pressure of solution decreses because less number of molecules of only one of the liquids escape from the solution.
D. A-B interactions are weaker than those between A-A or B-B.

Correct Answer – d
if two liquids on mixing are to form a minimum boiling azeotrope, the vapour pressure of the solution formed must be maimum (boiling point will be minimum). This can happen if A -B interactions are weaker than both A-A and B-B interactions.
