Vedclass · Answer

(D) The given conversion involves the reduction of a carboxylic acid group $(-COOH)$ to a primary alcohol $(-CH_2OH)$ while leaving the ketone $(-COCH_3)$,amide $(-CONH_2)$,and nitrile $(-CN)$ groups unaffected.$B_2H_6$ (diborane) is a selective electrophilic reducing agent that reduces carboxylic acids to primary alcohols much faster than it reduces other functional groups like ketones,amides,or nitriles under controlled conditions.$LiAlH_4$ is a strong reducing agent that would reduce all these groups ($-COOH$,$-COCH_3$,$-CONH_2$,$-CN$).$NaBH_4$ is a milder reducing agent but is generally not effective for reducing carboxylic acids directly.$H_2/Pd$ would reduce the ketone and potentially the nitrile group.Therefore,$B_2H_6$ is the most suitable reagent.
