Question

Draw 3 different reaction pathways for meta, ortho, and parasubstitution of a halogen (e.g. Br2 in FeBr3) onto nitro benzene.Each pathway should have all resonance structures.



After you have the resonance structures for each substitutiondrawn, examine them carefully and decide which set of resonancestructures is more (or less stable), and decide whether anitro-group will direct electrophilic aromatic substitution tooccur at the ortho and/or meta and/or para positions (relative tothe nitro group).
