Question

The correct match between items I and II is:

	Item - I (Mixture)		Item - II (Separation method)
(A)	H2O : Sugar	(P)	Sublimation
(B)	H2O : Aniline	(Q)	Recrystallization
(C)	H2O : Toluence	(R)	Steam distillation
		(S)	Differential extraction

पर्याय

• (A) → (S); (B) → (R); (C) → (P)

• (A) → (Q); (B) → (R); (C) → (S)

• (A) → (R); (B) → (P); (C) → (S)

• (A) → (Q); (B) → (R); (C) → (P)

Answer 1

(A) → (Q); (B) → (R); (C) → (S)

Explanation:

1. Sugar does not chemically react with water, and when water is heated, sugar dissolves completely. On cooling sugar solution, sugar recrystallises back.
2. Although aniline is not soluble in water, it is very volatile. Hence, it can be separated from water by steam distillation.
3. Toluene is insoluble as well as non-volatile in steam. Hence, they can be separated by differential extraction metbod.
