Nucleophilic aromatic substitution is possible, but involves substitution of a typical leaving group rather than a hydrogen atom. Remembering that SN2 and SN1 mechanisms are not viable at sp2 carbons, propose a mechanism for substitution of an aryl bromide by methoxide. Rank the relative reactivates of the following substrates, justifying your answers with resonance structures of key intermediates.
