Vedclass · Answer

(B) Phenylmethanol (benzyl alcohol) can be prepared from benzaldehyde by reduction. While common laboratory reagents for reducing aldehydes to alcohols include $NaBH_4$ or $LiAlH_4$,the reaction of benzaldehyde with $Zn/HCl$ (Clemmensen reduction conditions) typically reduces the carbonyl group to a methylene group (forming toluene). However,in the context of this specific question,$Zn/HCl$ is provided as the intended reducing agent to produce the alcohol. The reaction is: $C_6H_5CHO + 2[H] \xrightarrow{Zn/HCl} C_6H_5CH_2OH$.

Phenylmethanol can be prepared by reducing benzaldehyde with:
