Question:
If two liquids A and B form minimum boiling azeotrope at some specific
composition then _______________.
(i) A–B interactions are stronger than those between A–A or B–B.
(ii) vapour pressure of solution increases because more number of
molecules of liquids A and B can escape from the solution.
(iii) vapour pressure of solution decreases because less number of
molecules of only one of the liquids escape from the solution.
(iv) A–B interactions are weaker than those between A–A or B–B.
Solution:
Option (i) A–B interactions are stronger than those between A–A or B–B is the answer.
