Describe the use of a separatory funnel in the extraction of an organic compound.

Explain the principle of paper 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

$(ii)$ 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.
