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

Which are the types of chromatography?

Match List-$I$ with List-$II$:

List-$I$ (Mixture)	List-$II$ (Separation Technique)
$A$. $CHCl_3 + C_6H_5NH_2$	$I$. Steam distillation
$B$. $C_6H_{14} + C_5H_{12}$	$II$. Differential extraction
$C$. $C_6H_5NH_2 + H_2O$	$III$. Distillation
$D$. Organic compound in $H_2O$	$IV$. Fractional distillation

How will you separate a mixture of two organic compounds which have different solubilities in the same solvent?

$A$ chromatography column,packed with silica gel as the stationary phase,was used to separate a mixture of compounds consisting of $(A)$ benzanilide,$(B)$ aniline,and $(C)$ acetophenone. When the column is eluted with a mixture of solvents,hexane: ethyl acetate $(20: 80)$,the sequence of obtained compounds is:
