Question

The correct match between items of List-I and List-II is

	List - I		List - II
(A)	Coloured impurity	(P)	Steam distillation
(B)	Mixture of o - nitrophenol and p -nitrophenol	(Q)	Fractional distillation
(C)	Crude Naphtha	(R)	Charcoal treatment
(D)	Mixture of glycerol and sugars	(S)	Distillation under reduced pressure

• A. $(\text{A})-(\text{R}),(\text{B})-(\text{S}),(\text{C})-(\text{P}),(\text{D})-(\text{Q})$
• B. $(\text{A})-(\text{P}),(\text{B})-(\text{S}),(\text{C})-(\text{R}),(\text{D})-(\text{Q})$
• C. $(\text{A})-(\text{R}),(\text{B})-(\text{P}),(\text{C})-(\text{Q}),(\text{D})-(\text{S})$
• D. $(\text{A})-(\text{R}),(\text{B})-(\text{P}),(\text{C})-(\text{S}),(\text{D})-(\text{Q})$

Answer 1

Answer: (C)

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