Raoult’s law applies to an ideal solution in which interactions between A and B molecules are similar in strength to interactions between A molecules in pure liquid A, and interactions between B molecules in pure liquid B.

The solid line in the attached figure represents the vapor pressure of $CS_{2}$ as a function of mole fraction in a non-ideal solution of $CS_{2}$ and acetone. The dotted line is the ‘Raoult’s law’ line shown for reference.

What might account for the deviation from Raoult’s law experienced by this solution?

A

The intermolecular forces between acetone and $CS_{2}$ are stronger than they are in pure acetone or in pure $CS_{2}$.

B

The intermolecular forces between acetone and $CS_{2}$ are weaker than they are in pure acetone or in pure $CS_2$.

C

The solution is highly concentrated in $CS_{2}$.

D

Acetone and $CS_{2}$ are both polar liquids.
