A solution of chloroform, CHCl₃, and acetone, (CH₃)₂CO, exhibits a negative deviation from Raoult's law. This result implies that A) chloroform-chloroform interactions are stronger than chloroform-acetone interactions. B) chloroform-chloroform interactions are weaker than chloroform-acetone interactions. C) acetone-acetone interactions are stronger than chloroform-acetone interactions. D) acetone-acetone interactions are weaker than chloroform-acetone interactions. E) Both B and D. F) Both A and C.

Question

Quizplus · Accepted Answer

A negative deviation from Raoult's law indicates that the vapor pressure of the solution is lower than the vapor pressure predicted by Raoult's law. This implies that the interactions among the components are weaker than in the pure components. Specifically, it suggests that the chloroform-chloroform and acetone-acetone interactions are weaker than the chloroform-acetone interactions, which is consistent with options B and D. Therefore, the best choice is E, which includes both B and D.
