Choose the correct answer from the options given below:
| \textList-I | \textList-II | ||
| (Mixtures/Sample) | (Technique used for purification) | ||
| (A) | Glycerol from spent lye | (I) | Steam distillation |
| (B) | Chloroform + Aniline | (II) | Fractional distillation |
| (C) | Fractions of crude oil | (III) | Distillation under reduced pressure |
| (D) | Aniline + Water | (IV) | Distillation |
Options
- A\mathrm{I}\mathrm{II}\mathrm{III}
- B\mathrm{I}\mathrm{III}\mathrm{II}
- C\mathrm{III}\mathrm{II}\mathrm{I}
- D\mathrm{II}\mathrm{I}\mathrm{III}
Correct answer
C. \mathrm{III}\mathrm{II}\mathrm{I}
Step-by-step solution
- Chloroform (b.p. ) and aniline (b.p. 457) are easily separated by the technique of distillation as both the liquids having sufficient difference in their boiling points.
- The fractions of crude oil in petroleum industry is separated using fractional distillation due to less difference in boiling points of liquids.
- Glycerol can be separated from spent-dye using distillation under reduced pressure.
- Aniline is separated by steam distillation from aniline-water mixture.
