A) A - B interactions are stronger than A - A and B - B interactions
B) A - B interactions are weaker than A - A and B - B interactions
C) vapour pressure of solution is more than the pure components
D) vapour pressure of solution is less since only one component vaporises.
Correct Answer: A
Solution :
Since the new interactions (A - B) are stronger than (A - A) and (B - B) interactions, the solution shows negative deviation, i.e., less vapour pressure and hence higher boiling point.You need to login to perform this action.
