Question

Match the solution in Column I with its nature in Column II. Column I: (A) Benzene + toluene, (B) Ethanol + water, (C) Benzene + chloroform, (D) Acetone + chloroform. Column II: (P) Non-ideal solution, (Q) Ideal solution, (R) ΔH_mix > 0, (S) ΔH_mix < 0.

Correct answer: A→Q; B→P,R; C→P,R; D→P,S. Benzene + toluene ≈ ideal (A→Q). Ethanol + water: positive deviation, endothermic (B→P,R). Benzene + chloroform: positive deviation (C→P,R). Acetone + chloroform: negative deviation via H-bonding, exothermic (D→P,S).
