Vedclass · Answer

(D) $NaBH_4$ (Sodium borohydride) is a selective reducing agent that reduces aldehydes and ketones to alcohols. It does not reduce carboxylic acid derivatives like acid chlorides $(RCOCl)$ or esters $(RCOOR')$ to alcohols under normal conditions. - $CH_3CH_2CHO$ (Aldehyde) is reduced to $CH_3CH_2CH_2OH$ (Alcohol). - $CH_3CH_2COCH_2CH_3$ (Ketone) is reduced to $CH_3CH_2CH(OH)CH_2CH_3$ (Alcohol). - $CH_3COCl$ (Acid chloride) is reduced to an aldehyde or alcohol only with stronger reducing agents like $LiAlH_4$,but $NaBH_4$ is generally too weak to reduce it to alcohol. - $CH_3COOCH_2CH_3$ (Ester) is not reduced by $NaBH_4$. However,in the context of standard chemistry problems,acid chlorides and esters are both considered non-reactive towards $NaBH_4$ for reduction to alcohols. Given the options,$CH_3COCl$ and $CH_3COOCH_2CH_3$ both do not give alcohols. Typically,$NaBH_4$ is known for not reducing esters. Thus,the most appropriate answer is $D$.

Which of the following does not give alcohol with $NaBH_4$?
