Question

Match the following-

List 1	List 2
A.Coloured impurity	P.Steam distillation
B.Mixture of o-nitrophenol and p-nitrophenol	Q.Fractional distillation
C.Crude Naphtha	R.Charcoal treatment
D.Mixture of glycerol and sugars	S.Distillation under reduced pressure

A.A-R , B-S, C-P, D-Q
B.A-R , B-P, C-S, D-Q
C.A-P , B-S, C-R, D-Q
D.A-R , B-P, C-Q, D-S

Answer 1

We know that the process of evaporating or boiling a liquid and condensing its vapour. purification or separation of mixture by using different evaporation rates or boiling points of their components is known as distillation.

Complete step by step solution
It is known that Charcoal treatment helps in removing the coloured impurities through adsorption.
We studied that steam distillation separates the mixture of o-nitrophenol and p-nitrophenol. The o-nitrophenol is steam volatile due to its intramolecular hydrogen bonding, and the para isomer is not volatile.
Fractional distillation helps in separating crude naphtha. Naphtha is a flammable liquid hydrocarbon mixture.
Distillation under reduced pressure separates the mixture of glycerol and sugars. Vacuum distillation helps in lowering the boiling point and prevents decomposition.
So we can deduce that the correct answer for the above question is,. A-R , B-P, C-Q, D-S

So, the correct answer is option D.

Additional information
The process of evaporating or boiling of liquid and condensing its vapour. purification or separation of mixture by using different evaporation rates or boiling points of their components . Fractional distillation is the separation of a mixture into its component parts, or fractions. Chemical compounds are separated by heating them together in a temperature at which one or more fractions of the mixture will vaporize. It uses distillation to fractionate. Fractional distillation is that the tactic of separation of a mix into its component parts, or fractions.

Notes Basically vacuum distillation is the distillation which is performed under reduced pressure, which allows the purification of compounds not readily distilled at ambient pressures or simply to save time or energy. This technique helps on separating compounds based on differences in boiling points
