Match List I with List II: 

Choose the correct answer from the options given below:

Distillation is used to separate liquids having a large difference in boiling points. Chloroform and aniline have boiling points of approximately $$334\ K$$ and $$457\ K$$ respectively, making simple distillation suitable for their separation.

Therefore,

$$A \rightarrow (IV)$$

Fractional distillation is employed for separating mixtures of miscible liquids with closely spaced boiling points. A major industrial application is the separation of crude oil into its various fractions.

Therefore,

$$B \rightarrow (III)$$

Steam distillation is used for compounds that are steam volatile and immiscible with water. Aniline satisfies these conditions and can be separated from aniline-water mixtures by steam distillation.

Therefore,

$$C \rightarrow (II)$$

Distillation under reduced pressure is used for liquids having high boiling points that may decompose on heating at atmospheric pressure. Glycerol is separated from spent-lye using this technique because its boiling point is high and it undergoes decomposition upon prolonged heating.

Therefore,

$$D \rightarrow (I)$$

Hence, the correct matching is

$$A-(IV),\ B-(III),\ C-(II),\ D-(I)$$
