JEE Main 2025 — 2 April, Evening Shift — Question 3

Match List-I with List-II.

List-I (Purification technique)List-II (Mixture of organic compounds)
(A) Distillation (simple)(I) Diesel + Petrol
(B) Fractional distillation(II) Aniline + Water
(C) Distillation under reduced pressure(III) Chloroform + Aniline
(D) Steam distillation(IV) Glycerol + Spent-lye

Choose the correct answer from the options given below.

  1. Option A:

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

  2. Option B:

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

    Correct
  3. Option C:

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

  4. Option D:

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

Answer: B

Step-by-step solution

Boiling point of aniline is 547 K and B.P. of CHCl3\mathrm{CHCl}_{3} is 334 K . So, they are separated by simple distillation.
