Match the Column - List - I List - II (A) Acetone + CHCl 3 ​ (P) Δ S mix. ​ > 0 (B) Ethanol + Water (Q) Δ V mix. ​ > 0 (C) C 2 ​ H 5 ​ Br + C 2 ​ H 5 ​ I (R) Δ H mix. ​ < 0 (D) Acetone + Benzene (S) Maximum boiling azeotropes (T) Minimum boiling azeotropes

TestHub · Accepted Answer

(A) Acetone + CHCl₃ shows a negative deviation from Raoult's law. Here, $Δ S > 0$ , $Δ H < 0$ , and $Δ V < 0$ , forming maximum boiling azeotropes.

(B) Ethanol + Water shows a positive deviation from Raoult's law. Here, $Δ S > 0$ , $Δ H > 0$ , and $Δ V > 0$ , forming minimum boiling azeotropes.

(C) C₂H₅Br + C₂H₅I forms an ideal solution with no azeotropes. For this solution, $Δ H = 0$ and $Δ V = 0$ .

(D) Acetone + Benzene shows a positive deviation from Raoult's law. Here, $Δ H > 0$ , $Δ V > 0$ , and $Δ S > 0$ , forming minimum boiling azeotropes.
