AIIMS 2019 Chemistry Selective Reduction MCQ Question

LiAlH₄ and NaBH₄ are selective reducing agents that can reduce aldehydes (−CHO) to alcohols but do not affect alkynes (C≡C) due to the lack of reactivity towards the triple bond. In the presence of H₂O or C₂H₅OH, these reagents will not engage with the C≡C bond, as they require stronger conditions or different reagents for such reductions. Other options are not applicable in this context, as they do not provide relevant alternatives or information regarding the reactivity of these reducing agents. Understanding the selectivity of reducing agents is crucial for predicting reaction outcomes in organic chemistry.
