उत्तर
A-B attraction force remains the same as A-A and B-B.
Explanation:
Raoult’s Law is obeyed only by ideal solutions. For a solution to be ideal:
The intermolecular forces between A-B must be equal to those between A-A and B-B. There should be no heat change upon mixing (ΔHₘᵢₓ = 0). The total volume of solution must be equal to the sum of volumes of components (i.e., no volume change on mixing). Therefore, A-B = A-A = B-B in strength for an ideal solution.
