Q.

Match List I with List II:

List I (Mixture)List II (Method of Separation)
A. CHCl + CHNHI. Distillation under reduced pressure
B. Crude oil in petroleum industryII. Steam distillation
C. Glycerol from spent-lyeIII. Fractional distillation
D. Aniline-waterIV. Simple distillation

Choose the correct answer from the options given below:

  1. A

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

  2. B

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

  3. C

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

  4. D

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

Solution

CHCl and aniline have a large boiling-point difference and don't decompose → simple distillation (IV).

Crude oil has many components with closely-spaced boiling points → fractional distillation (III).

Glycerol is high-boiling and thermally sensitive → distillation under reduced pressure (I).

Aniline is immiscible with water and steam-volatile → steam distillation (II).

A-IV, B-III, C-I, D-II.
