Correct answer
B. A-IV, B-III, C-II. D-I
Step-by-step solution
A mixture of chloroform and aniline can be separated by distillation. The boiling point of chloroform is C, and that of aniline is 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.
