Nitro Reduction - LiAlH4 - Common Organic Chemistry

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. http://www.commonorganicchemistry.com/Rxn_Pages/Nitro_Reduction/Nitro_Reduction_Index.htm sicko hoodie ian connor
