Vedclass · Answer

(B) Carboxylic acids are reduced to primary alcohols by lithium aluminium hydride $(LiAlH_4)$ or more selectively with diborane $(B_2H_6)$.$B_2H_6$ is a specific reagent that reduces the carboxylic acid group to a primary alcohol while leaving other functional groups like esters,nitro,or halo groups unaffected.$NaBH_4$ is not strong enough to reduce the carboxylic acid group.$Zn-Hg / 	ext{conc. } HCl$ is used for Clemmensen reduction,which reduces aldehydes and ketones to alkanes,not carboxylic acids to alcohols.$H_2, Pd / C$ is generally used for the hydrogenation of alkenes and alkynes and does not reduce carboxylic acids.

The reagent that can reduce the carboxylic acid group to the corresponding alcohol is
