Which of the following reactions is an example of Clemmensen reduction?
Which of the following reactions is an example of Clemmensen reduction?
Show Hint
There are two main named reactions to reduce a carbonyl group (aldehyde/ketone) completely to an alkane (-CH$_2$-):
1. Clemmensen Reduction: Uses Zn-Hg and conc. HCl. It is performed in acidic conditions and is not suitable for acid-sensitive compounds.
2. Wolff-Kishner Reduction: Uses NH$_2$NH$_2$ and a strong base (KOH). It is performed in basic conditions and is not suitable for base-sensitive compounds.

- R-CO-Cl + H$_2 \xrightarrow{Pd/BaSO_4}$ R-CHO + HCl
- R-CHO $\xrightarrow{(i)NH_2NH_2, (ii)KOH/Glycol}$ R-CH$_3$
- R-CO-OC$_2$H$_5 \xrightarrow{1. DIBAL-H, 2. H_2O}$ R-CHO + C$_2$H$_5$OH
- R-CO-CH$_3 \xrightarrow{Zn-Hg/HCl}$ R-CH$_2$-CH$_3$
