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

Answer :

If two liquids A and B form minimum boiling azeotrope at some specific composition then the bonds between A-B is weaker than A-A and B-B bonds because bonds are breaking at a lower temperature for a new interaction.


Thus, statement (iv) is true and others are false.
