Using column chromatography,a mixture of two compounds '$A$' and '$B$' was separated. '$A$' eluted first,this indicates '$B$' has

Describe the simple distillation method for the purification of liquid compounds.

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

The method used for the separation of the mixture of products ($B$ and $C$) obtained in the following reaction is:

Which are the methods of purification of organic compounds?

Given below are two statements: One is labelled as Assertion $A$ and the other is labelled as Reason $R$.
Assertion $A$: Thin layer chromatography is an adsorption chromatography.
Reason $R$: $A$ thin layer of silica gel is spread over a glass plate of suitable size in thin layer chromatography which acts as an adsorbent.
In the light of the above statements,choose the correct answer from the options given below.
