WebThe questions states: "Write a balanced equation for the reaction: Reduction of nitrobenzene with NaBH4." I don't think its asking for the mechanism. I didnt think it would work either. I Put 2 [O] to replace NaBH4 and just replaced the NO2 with NH2 but i think im wrong. Ph-NO2 + 2 [H] ---> Ph-NH2 if you're going down that route.

Can LiAlH4 reduce nitro group? Lithium aluminum hydride (LiAlH4) represents a very versatile reducing agent that is extremely useful in synthetic organic chemistry. WebApr 12, 2024 · 1 Answer. Though, the carbonyls are reduced to alcohols after the treatment with L i A l H X 4 ,here the C = O double bond is part of the Amide ( − C O N H X 2) group, and this group has definitely different chemical functionality than pure carbonyls.So, though both the aldehyde (or, keto) and amides have same C = O double bonds, but thir ...
WebLiAlH4 is a rather hard nucleophilic reductant (HSAB Principle) which means it reacts with electrophiles, and alkenes are not electrophiles. The main reason is that Al needs to remove its hydride.
