On which principle does the solute move on chromatography paper?

State True or False for the following statements:
$(i)$ The volatile liquid is purified by fractional distillation or simple distillation.
$(ii)$ Two liquids are separated by fractional distillation.
$(iii)$ Liquids with a small difference in boiling points are separated by fractional distillation.
$(iv)$ Liquids with a large difference in boiling points are separated by fractional distillation.

Among the following,in which type of chromatography,both stationary and mobile phases are in liquid state?

Match column $-I$ and column $-II$ with the correct relation:

Column $-I$	Column $-II$
$(i)$ Liquid boiled at low temperature	$(a)$ Fractional distillation
$(ii)$ Glycerol from lye	$(b)$ Simple distillation
$(iii)$ The liquid with lower boiling point condenses first	$(c)$ Steam distillation
$(iv)$ The liquid with higher boiling point condenses first	$(d)$ Distillation under reduced pressure

$A$ flask contains a mixture of isohexane and $3-$methylpentane. One of the liquids boils at $63^{\circ}C$ while the other boils at $60^{\circ}C$. What is the best way to separate the two liquids and which one will be distilled out first?

Suggest a method for the purification of camphor contaminated with salt.
