- A Wolff - Kishner reaction
- B Rosenmund reaction
- C Etard reaction
- D Hell - Volhard - Zelinsky reaction
Answer & Solution
Correct Answer
(D) Hell - Volhard - Zelinsky reaction
Step-by-step Solution
Detailed explanation
Hell - Volhard - Zelinsky Reaction : It is \(\alpha \) - subtitution when a carboxylic acid having \(\alpha \) - hydrogens is treated with chlorine or bromine in presence of small amount of red phosphorous. \(R-C{{H}_{2}}COOH\,+\,{{X}_{2}}\,\xrightarrow{P}\)…
