Text Solution

Verified by Experts
The correct answer is:
A

For an ideal solution, the or type intermolecular interaction is nearly equal to A

B type interaction. Here, a mixture of bromoethane and chloroethane is an example of ideal solution.
On the other hand, chloroform and acetone mixture is an example of non-ideal solution having negative deviation. So, (A-A) or (B-B) interaction must be weaker than A-B type interaction. While ethanol-acetone mixture shows. positive deviation due to weaker interaction in comparison to or interaction.
