The correct Answer is:
To solve the question, we need to match the compounds in Column-I with the corresponding conditions in Column-II based on their behavior in solutions, particularly in relation to Raoult's law and the concepts of mixing enthalpy (ΔH), mixing volume (ΔV), and mixing entropy (ΔS). ### Step-by-Step Solution: 1. **Identify the behavior of each mixture:** - **(A) Acetone + CHCl₃:** This mixture is known to show a negative deviation from Raoult's law. Therefore, it will have ΔS(mix) > 0 and ΔH(mix) < 0. This means it can be matched with (r) ΔH(mix) < 0. - **(B) Ethanol + Water:** This mixture shows a positive deviation from Raoult's law, which means it has ΔV(mix) > 0. It is also known for forming minimum boiling azeotropes, so it matches with (t) ΔV(mix) > 0. - **(C) C₂H₅Br + C₂H₅I:** These compounds are ideal solutions and do not show significant deviations from Raoult's law. Thus, they will have ΔS(mix) > 0, which leads to matching with (p) ΔS(mix) > 0. - **(D) Acetone + Benzene:** This mixture shows a positive deviation from Raoult's law, indicating ΔV(mix) > 0 and is associated with minimum boiling azeotropes. Therefore, it matches with (t) ΔV(mix) > 0. 2. **Match the results:** - (A) Acetone + CHCl₃ → (r) ΔH(mix) < 0 - (B) Ethanol + Water → (t) ΔV(mix) > 0 - (C) C₂H₅Br + C₂H₅I → (p) ΔS(mix) > 0 - (D) Acetone + Benzene → (s) Maximum boiling azeotropes ### Final Matches: - A → r - B → t - C → p - D → s
