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

Explain why an organic liquid vaporises at a temperature below its boiling point during steam distillation.

What is adsorption chromatography? Write its types.

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

Explain the principle of paper chromatography.

The fragrance of flowers is due to the presence of some steam volatile organic compounds called essential oils. These are generally insoluble in water at room temperature but are miscible with water vapour in the vapour phase. $A$ suitable method for the extraction of these oils from the flowers is:
