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	$1$. Crystallisation
$B$. Liquid that decomposes at its boiling point	$2$. Distillation under reduced pressure
$C$. Steam volatile liquid	$3$. Steam distillation
$D$. Two liquids which have boiling points close to each other	$4$. Fractional distillation
$E$. Two liquids with large difference in boiling points	$5$. Simple distillation

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

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 of the following compounds can be separated by the steam distillation method?

What is the purification method based on the principle that the compound and the impurities have different solubilities in a given solvent?
