Match List I with List II

  LIST I (Technique)   LIST II (Application)
A. Distillation I. Separation of glycerol from spent-lye
B. Fractional distillation II. Aniline - Water mixture
C. Steam distillation III. Separation of crude oil fractions
D. Distillation under reduced pressure IV. Chloroform-Aniline

Choose the correct answer from the options given below:

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

Solution

A mixture of chloroform and aniline can be separated by distillation. The boiling point of chloroform is 60°C, and that of aniline is 189°C. Therefore, distillation can be used to separate a mixture of chloroform and aniline.

Fractional distillation is the process by which oil refineries separate crude oil into different, more useful hydrocarbon products based on their relative molecular weights in a distillation tower.

Steam Distillation is a separation process for temperature-sensitive substances. It is a particular type of distillation. Another way around is a method for separating miscible liquid bases depending upon their volatilities. Aniline - Water mixture can be separated by this technique.

For separating glycerol from spent-lye is distillation under reduced pressure because glycerol has a high boiling point and since in this method the external pressure is lowered, it boils at a lower temperature.

Hence option B is the answer.
