A solution of two liquids,A and B,shows negative deviation from Raoult's law.This means that:
A)The molecules of A interact strongly with other A-type molecules.
B)The two liquids have a positive heat of solution.
C)Molecules of A interact weakly,if at all,with B molecules.
D)The molecules of A hinder the strong interaction between B molecules.
E)Molecules of A interact more strongly with B than A with A,or B with B.

Question

Quizplus · Accepted Answer

Negative deviation from Raoult's law indicates that the interactions between the different molecules in the solution (A and B) are stronger than the interactions among the molecules of each liquid separately. This leads to a lower vapor pressure than predicted by Raoult's law, which is consistent with choice E.
