Options
- A(A)-(III), (B)-(I), (C)-(II)
- B(A)-(III), (B)-(II), (C)-(I)
- C(A)-(II), (B)-(III), (C)-(I)
- D(A)-(I), (B)-(II), (C)-(III)
Correct answer
B. (A)-(III), (B)-(II), (C)-(I)
Step-by-step solution
n-Hexane and n-heptane form an ideal solution because their intermolecular interactions are similar to those in their pure states. For an ideal solution, _ mix V = 0 and _ mix H = 0 . Thus, (A) matches with (III). Ethanol and water form a non-ideal solution showing a positive deviation from Raoult's law because the addition of water breaks the hydrogen bonds between ethanol molecules. This leads to _ mix H > 0 and the formation of a minimum boiling azeotrope. Thus, (B) matches with (II). Nitric acid and water form
