A solution containing components A and B follows Raoult's law when

Options

A. A - B attraction force is greater than A - A and B-B
B. A - B attraction force is less than 4 - A and B-B
C. A - B attraction force remains same as A - A and B-B
D. volume of solution is different from sum of volumes of solute and solvent.

Answer

C

Explanation

Raoult.s law is valid for ideal solutions only. The element of non-ideality enters into the picture when the molecules of the solute and solvent effect each others intermolecular forces. A solution containing components of A and B behaves as an ideal solution when A-B attraction force remains same as A-A and B-B.
