When chlorine is treated with carboxylic acid in the presence of red phosphorus then chloro acid will be formed, this reaction is known as
1 Hunsdicker reaction
2 Hell-Volhard - zelinsky reaction
3 Friedel - crafts reaction
4 Rosenmund reduction
Explanation:
The reaction of chlorine on carboxylic acids to form alpha chloro acids is called Hell-Volhard-Zelinsky reaction. \(RCH _2- COOH \stackrel{ i. X _2 \text { /reclphosphorus,iiwater }}{\longrightarrow} RCHX - COOH\) In this reaction, alpha hydrogen of carboxylic acids is replaced with halogen atom.
