Ethylene has a high $b.p.$ and high vapour pressure at $100\,^{\circ}C$ and does not dissolve in water. Hence,ethylene is separated by this method:

Which one of the following methods is suitable to separate a mixture of $n$-pentane and toluene?

Aniline is separated from a mixture by

Which substance is used in the purification of bone charcoal?

Consider the following table$-$

Column-$I$	Column-$II$
$(A).$ Best and latest technique for isolation,purification and separation of organic compounds	$(i).$ Chromatography
$(B).$ In Lassaigne's test for $N$	$(ii).$ Vacuum distillation (distillation under reduced pressure)
$(C).$ In Lassaigne's test for $S$	$(iii).$ Violet coloured complex is formed
$(D).$ Aniline is purified from water by	$(iv).$ Prussian blue coloured complex is formed
$(E).$ Glycerol is purified from spent lye	$(v).$ Steam distillation

The correct match is $-$
