Question

Given reaction, ${C_6}{H_5}OH + ClCOC{H_3}\xrightarrow{{aq.NaOH}}{C_6}{H_5}OCOC{H_3}$ is an example of:
A.Dow’s reaction
B.Reimer-Tiemann reaction
C.Schotten-Baumann reaction
D.Kolbe’s reaction

Answer 1

Hint: We need to know the reaction between an acid chloride and an alcohol. Acid chlorides generally react with alcohols to form esters. As in the replacement reaction between a carboxylic acid and an alcohol, an ester is a chemical compound formed from an acid (organic or inorganic) in which at least one –OH hydroxyl group is substituted by a –O– alkyl (alkoxy) group.

Complete answer:
We must have to know that the Schotten–Baumann reaction is a mechanism for making amides from amines and acid chlorides. It also applies to the process of converting acid chloride to esters. The Schotten-Baumann reaction denotes the formation of an ester(${C_6}{H_5}OCOC{H_3}$) from an acid chloride($ClCOC{H_3}$) and an alcohol (${C_6}{H_5}OH$) . The following reaction is an example of ester formation.
Therefore, the correct option is option (C).
Chlorobenzene is heated with sodium hydroxide under pressure to produce phenol in Dow's reaction.
Hence, option (A) is incorrect.
The Reimer-Tiemann reaction is an organic reaction which uses chloroform to convert phenol to an o-hydroxy benzaldehyde.
Hence, option (B) is incorrect.
The Kolbe–Schmitt reaction is a carboxylation reaction in which sodium phenoxide is heated with carbon dioxide under pressure and then treated with sulfuric acid to produce salicylic acid.
Hence, option (D) is incorrect.

Note:
It must be noted that the usage of a two-phase solvent scheme, consisting of water and an organic solvent, is often referred to as "Schotten–Baumann reaction conditions." The acid formed in the reaction is neutralised by the base in the water phase, while the starting materials and product remain in the organic phase, which is usually dichloromethane or diethyl ether. In the industrial development of amides, the Schotten – Baumann reaction is used. It's an acid chloride-based approach for synthesising amides.
