Reactive species in nitration of benzene

WebHere's the general reaction for the nitration of benzene. So we start off with benzene, and to it, you add concentrated nitric and concentrated sulfuric acids. And that puts a nitro group … WebThe above said positions (ortho and para) are the most reactive towards an electron-poor electrophile, thus promoting electrophillic substitution reaction. The methyl group hence makes it around 25 times more reactive than benzene hence making its nitration more easier than that of benzene.
