Question

Match Column-I (Reaction) with Column-II (Product formed) and mark the appropriate choice:

Column-I (Reaction) (a) Gabriel synthesis (b) Kolbe synthesis (c) Williamson synthesis (d) Etard reaction

Column-II (Product formed) (i) Benzaldehyde (ii) Ethers (iii) Primary amines (iv) Salicylic acid

A

(a)-(iii), (b)-(i), (c)-(ii), (d)-(iv)

B

(a)-(ii), (b)-(iii), (c)-(i), (d)-(iv)

C

(a)-(iv), (b)-(iii), (c)-(i), (d)-(ii)

D

(a)-(iii), (b)-(iv), (c)-(ii), (d)-(i)

Step-by-Step Solution

Let's match each name reaction with its corresponding product:

  1. Gabriel phthalimide synthesis: This reaction is used exclusively for the preparation of pure aliphatic primary amines from alkyl halides.
  2. Kolbe synthesis: In this reaction, phenol is treated with sodium hydroxide and CO2CO_2, followed by acidification, to yield 2-hydroxybenzoic acid, commonly known as salicylic acid.
  3. Williamson synthesis: This is a classic method for the preparation of symmetrical and unsymmetrical ethers by reacting an alkyl halide with a sodium alkoxide.
  4. Etard reaction: This reaction involves the partial oxidation of toluene using chromyl chloride (CrO2Cl2CrO_2Cl_2) to form benzaldehyde.

Therefore, the correct matching is (a)-(iii), (b)-(iv), (c)-(ii), (d)-(i).
