Question

When chlorine is treated with carboxylic acid in the presence of red phosphorus then chloro acid will be formed, this reaction is known as: (A) Hunsdicker reaction (B) Hell-Volhard - zelinsky reaction (C) Friedel - crafts reaction (D) Rosenmund reduction

Tardigrade Admin · Accepted Answer

The reaction of chlorine on carboxylic acids to form alpha chloro acids is called Hell-Volhard-Zelinsky reaction.

RC H_{2} ​ - COO H i . X_{2} ​/ red phosphorus, ii . water ​ \to RC H X - COO H

In this reaction, alpha hydrogen of carboxylic acids is replaced with halogen atom.
