What is adsorption chromatography? Write its types.

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

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 $-$

The correct match between items of List-$I$ and List-$II$ is:

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

State True or False for the following statements regarding steam distillation:
$(i)$ The liquid is boiled at a temperature lower than its normal boiling point.
$(ii)$ The vapour pressure of the liquid is less than the atmospheric pressure.
$(iii)$ The sum of the vapour pressure of the liquid and the vapour pressure of water is equal to the atmospheric pressure.
$(iv)$ The mixture of organic liquid and water is obtained as the distillate.
$(v)$ The condensation of the mixture of water vapour and organic liquid vapour takes place.

Which technique among the following is most appropriate for the separation of a mixture of $100 \ mg$ of $p-$nitrophenol and picric acid?
