Which purification method is used to separate liquids that have a sufficient difference in their boiling points?

The mixture of compounds $A$ and $B$ is passed through a column of $Al_2O_3$ by using alcohol as eluant. Compound $A$ is eluted in preference to compound $B$. Which of the compounds $A$ or $B$ is more readily adsorbed on the column?

Which of the following methods is used for the purification of organic compounds?

Match List-$I$ with List-$II$.

List-$I$ (Purification technique)	List-$II$ (Used to separate)
$A$. Simple distillation	$I$. Steam volatile compound
$B$. Fractional distillation	$II$. Two liquids with large difference in boiling points
$C$. Steam distillation	$III$. Liquid decomposing at its boiling point
$D$. Distillation under reduced pressure	$IV$. Two liquids with close boiling points

What is the difference between distillation,distillation under reduced pressure,and steam distillation?

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.
