Solution

The correct option is D Reduced pressure distillation
Reduced pressure distillation or vaccum distillation is used for the purification of high boiling organic liquids which decomposes at or below their boiling point.
Hence, option (d) is correct.

A liquid with high boiling point decomposes on simple distillation but it can be steam distilled for its purification. Explain how is it possible?

If a liquid compound decomposes at its boiling point, which method $(s)$ can you choose for its purification. It is known that the compound is stable at low pressure, steam volatile and insoluble in water.

Q. The substance has boiling point

563 K

, but it starts decomposing near this temperature. Which type of distillation process is suitable for its purification?

Match the type of mixture of compounds in Column I with the technique of separation / purification given in Column II.

	Column I		Column II
A	Two solids which have different solubilities in a solvent and which do not undergo reaction when dissolved in it	$(i)$	Steam distillation
B	Liquid that decomposes at its boiling point	$(i i)$	Fractional distillation
C	Steam volatile liquid	$(i i i)$	Simple distillation
D	Two liquids which have boiling points close to each other	$(i v)$	Distillation under reduced pressure
E	Two liquids with large difference in boiling points.	$(v)$	Crystallization

This method is used to purify liquids having very high boiling points and those, which decompose at or below their boiling points.
