On the basic of information given below mark the Correct option .Information:
(P)In bromoethane and choroethane mixture intermolar interactions of A.A and B.B tupesare nearly same as A .B type intersections.
(Q) In ethanol and acetone mixture A.A or B.B type inetermolecular interaction are stronger than A.B type interactions.
(R) In chloroform and acetone mixture A.A or B.B type intermolecular interactions are weaker than A. B type interactions.

Options

A. Solution (II) and (III) will follow Raoult's law
B. Solution (I) will follow Raoult's law
C. Solution (II) will show negative deviation from Raoult's law .
D. Solution (III) will show positive deviation from Raoult's law .

Answer

B

Explanation

Mixture of bromoethane and chloroethane is an ideal solution and will follow Raoult's law as intermolecular interactions of A-A and B-B type are nearly same as A-B type interactions.
