Clemmensen reduction

Vedclass · Answer

(A) $1$. The reduction of alkanones (ketones) to alkanes can be achieved using Clemmensen reduction.$2$. In Clemmensen reduction, the carbonyl group $(>C=O)$ is reduced to a methylene group $(-CH_2-)$ using zinc amalgam $(Zn-Hg)$ and concentrated hydrochloric acid $(HCl)$.$3$. The reaction is: $R-CO-R' + 4[H] \xrightarrow{Zn-Hg/HCl} R-CH_2-R' + H_2O$.$4$. Etard reaction is used for the oxidation of toluene to benzaldehyde. Rosenmund reduction is used for the reduction of acid chlorides to aldehydes. Haloform reaction is used for the detection of methyl ketones.

Which of the following reactions is preferentially used to prepare the corresponding alkanes from alkanones?
