\end{array}\) Choose the correct answer from the options given below:
  1. $(\mathrm{A})-(\mathrm{I}),(\mathrm{B})-(\mathrm{II}),(\mathrm{C})-(\mathrm{III}),(\mathrm{D})-(\mathrm{IV})$
  2. $(\mathrm{A})-(\mathrm{I}),(\mathrm{B})-(\mathrm{III}),(\mathrm{C})-(\mathrm{II}),(\mathrm{D})-(\mathrm{IV})$
  3. $(\mathrm{A})-(\mathrm{III}),(\mathrm{B})-(\mathrm{IV}),(\mathrm{C})-(\mathrm{II}),(\mathrm{D})-(\mathrm{I})$
  4. $(\mathrm{A})-(\mathrm{IV}),(\mathrm{B})-(\mathrm{II}),(\mathrm{C})-(\mathrm{I}),(\mathrm{D})-(\mathrm{III})$

Solution

- Chloroform (b.p. $334 \mathrm{~K}$ ) 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.
