Correct answer
D. (a) - (iii), (b) - (iv), (c) - (ii), (d) - (i)
Step-by-step solution
(a) Gabriel synthesis (iii) Primary amines Pthalimide is alkylated with primary or unbranched secondary alkyl halides or sulphonate. The product thus obtained is hydrolysed to give primary amines. Treatment of toluene with chromyl chloride in an inert solvent like CS ₂ or CCl ₄ forms an insoluble complex C ₆ H ₅ CH ( OCrCl ₂ OH )₂ which further on hydrolysis produces benzaldehyde.
