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

Accepted Answer

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 $CO_2$, 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 ($CrO_2Cl_2$) to form **benzaldehyde**.

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