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-acetone interactions are weaker than chloroform-chloroform interactions. C) acetone-acetone interactions are stronger than chloroform-acetone interactions. D) acetone-acetone interactions are weaker than chloroform-acetone interactions.

Quizplus · Accepted Answer

A negative deviation from Raoult's law indicates that the interactions between the different components of the mixture (in this case, chloroform and acetone) are stronger than the interactions within the pure components themselves. This means that chloroform-acetone interactions are stronger than either chloroform-chloroform or acetone-acetone interactions, which is what choice D states.
