Question
Write a note on Clemmensen reduction.Explain Clemmeusen’s reduction.Explain the reduction of carbonyl group into methylene group.
✓
Answer
- The carbonyl group
on reduciion with zinc amalgam $(Zn – Hg)$ in concentrated hydrochloric acid is converted into methylene group $(CH_2 -).$
- Aldehydes and kctoncs on reaction with $Zn – Hg$ in concentrated $HCl$ forms corresponding alkanes. ibis reduction is called Clemmensen reduction.
- Acetaldehyde on reduction with $Zn – Hg$ in concentrated $HCl$ forms ethane.
- Acetone on reduction with $Zn – Hg$ in concentrated $HCl$ forms propane.
