Vedclass · Answer

(B) The given reaction involves the selective reduction of a ketone group to a secondary alcohol while keeping the ester group $(-COOCH_3)$ intact.$LiAlH_4$ is a strong reducing agent that reduces both ketones and esters to alcohols.$NaBH_4$ is a selective reducing agent that reduces aldehydes and ketones to alcohols but does not reduce esters under normal conditions.$Ni, H_2$ (catalytic hydrogenation) would reduce both the ketone and the ester group.$Zn-Hg / HCl$ (Clemmensen reduction) reduces the ketone group to a methylene $(-CH_2-)$ group,not an alcohol.Therefore,$NaBH_4$ is the correct reagent for this selective reduction.
