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 attractive forces
B. A-B attraction force is less than A-A and B-B attractive forces
C. A-B attraction force remains same as A-A and B-B attractive forces
D. Volume of solution is different from sum of volumes of solute and solvent.

Answer

3

Explanation

At molecular level, ideal behaviour of the solutions can be explaines by considering two components `A` and `B`. In pure components, the intermolecular attractive interactions will be of types `A-A` and `B-B`, whereas in the binary solutions in addition to these interactions, `A-B` type of interactions will also be present.
