Vedclass · Answer

(D) The given reaction involves the reduction of an aldehyde group $(-CHO)$ to a methyl group $(-CH_3)$ in the presence of a hydroxyl group $(-OH)$.$1$. $Red \, P + HI$ is a strong reducing agent that reduces carbonyl groups to alkanes.$2$. $NH_2-NH_2 + OH^-$ (Wolff-Kishner reduction) reduces carbonyl groups to alkanes under basic conditions.$3$. $Zn(Hg) + HCl$ (Clemmensen reduction) reduces carbonyl groups to alkanes under acidic conditions.Since the substrate contains an alcohol group $(-OH)$,which is sensitive to acid,the Clemmensen reduction $(Zn(Hg) + HCl)$ might cause side reactions like dehydration or substitution. However,all three reagents are standard methods for reducing aldehydes/ketones to alkanes. Given the options,all are typically cited as reagents for this transformation.
