The nitro groups on the benzene ring in the reactant serve two purposes.One is to let you know what atoms in the reactant correspond to what atomsin the product. But what role do the nitro groups play electronically – whywould the reaction be much slower if these nitro groups weren’t attached tothose benzene carbons? Draw any relevant structures to support youranswer.
