Question
In Clemmensen Reduction carbonyl compound is treated with:
Options
Zinc amalgam + HCl
Sodium amalgam + HCl
Zinc amalgam + nitric acid
Sodium amalgam + HNO3
Solution
Zinc amalgam + HCl
Explanation:
Clemmensen reduction is used to convert carbonyl group to \[\ce{CH2}\] group as follows
\[\begin{array}{cc}
\phantom{}\backslash\phantom{..................}\backslash\phantom{}\\
\phantom{.......}\ce{C = O ->[Zn(Hg) + HCl] CH2}\phantom{..}\\
\phantom{}/\phantom{..................}/\phantom{}
\end{array}\]
Zinc amalgam and \[\ce{HCl}\] act as reagent in this reaction.
