On the basis of information given below mark the correct option.I. In bromo ethane and chloro ethane mixture,inter molecular interactions of A $$-$$ A and B $$-$$ B type are nearly same as $$A-B$$ type interactions.II. In ethanol and acetone mixture $$A-A$$ or $$B-B$$ type inter molecular interactions are stronger than $$A-B$$ type interactions.III. In chloroform and acetone mixture $$A-A$$ or $$B-B$$ type inter molecular interactions are weaker than $$A-B$$ type interactions.

Question

Infinity Learn · Accepted Answer

For an ideal solution, the $$A-A$$ or $$B-B$$ type inter molecular interaction are equal to $$A-B$$ type interactions. Here, a mixture of bromoethane and chloroethane is an example of ideal solution. So it follows Raoult's law.On the other hand, chloroform and acetone mixture is an example of $$non-ideal$$ solution having negative deviation. So, $$A-$$ A are $$B-$$ B type interactions must be stronger than $$A-B$$ type interaction. while $$ethanol-acetone$$ mixture shows positive deviation due to weak er $$A-B$$ interactions in comparison to $$A-A$$ are $$B-B$$ interactions.
