Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → A-IV, B-I, C-III, D-II
(A) Solvent used in perfumes — (IV) Ethanol. Ethanol dissolves the fragrant oils and evaporates easily, so it is the usual solvent for perfumes.
(B) Starting material for picric acid — (I) Phenol. Phenol gives 2,4,6-trinitrophenol (picric acid) on nitration (better via phenol-2,4-disulphonic acid).
(C) Wood spirit — (III) Methanol. Methanol was produced by the destructive distillation of wood, hence the name wood spirit.
(D) By-product of the soap industry used in cosmetics — (II) Glycerol. Saponification of fats gives soap and glycerol; glycerol is used in cosmetics and shaving soaps as a moisturiser.
