Match List-I with List-II. List-I (Purification technique) (A) Distillation (simple) (B) Fractional distillation (C) Distillation under reduced pressure (D) Steam distillation List-II (Mixture of organic compounds) (I) Diesel + Petrol (II) Aniline + Water (III) Chloroform + Aniline (IV) Glycerol + Spent-lye Choose the correct answer from the options given below.

1. (A)-(II), (B)-(IV), (C)-(I), (D)-(III)
2. (A)-(III), (B)-(I), (C)-(IV), (D)-(II)
3. (A)-(II), (B)-(III), (C)-(IV), (D)-(I)
4. (A)-(III), (B)-(IV), (C)-(II), (D)-(I)

Correct answer: (A)-(III), (B)-(I), (C)-(IV), (D)-(II)

Solution

The correct option matches each purification technique with the appropriate mixture: simple distillation is suitable for separating chloroform and aniline due to their differing boiling points, fractional distillation effectively separates diesel and petrol, distillation under reduced pressure is ideal for glycerol and spent-lye, and steam distillation is used for aniline and water, which are immiscible.
