Solution:
$\left(\right.\text{A}\left.\right)-\left(\right.\text{R}\left.\right),\left(\right.\text{B}\left.\right)-\left(\right.\text{P}\left.\right),\left(\right.\text{C}\left.\right)-\left(\right.\text{Q}\left.\right),\left(\right.\text{D}\left.\right)-\left(\right.\text{S}\left.\right)$
1. Coloured impurity $ \rightarrow $ Charcoal treatment
2. mixture of o – nitrophenol and p –nitrophenol $ \rightarrow $ Steam distillation(Both form intermolecular H-Bond)
3. Crude Naphtha $ \rightarrow $ Fractional distillation
4. mixture of glycerol and sugars $ \rightarrow $ Distillation under reduced pressure
