उत्तर
(A) → (Q); (B) → (R); (C) → (S)
Explanation:
- Sugar does not chemically react with water, and when water is heated, sugar dissolves completely. On cooling sugar solution, sugar recrystallises back.
- Although aniline is not soluble in water, it is very volatile. Hence, it can be separated from water by steam distillation.
- Toluene is insoluble as well as non-volatile in steam. Hence, they can be separated by differential extraction metbod.
