(a) Interpretation: How to synthesize the given compound using only a single nucleophilic aromatic substitution reaction is to be shown. Concept introduction: In a nucleophilic aromatic substitution reaction, the aromatic ring is attacked by a nucleophile. If these reactions are precedes though the benzyne intermediate formation, requires very extreme conditions like high temperature, a very strong base, or sometimes both. Since the benzyne intermediate is very highly unstable, undergoes a nucleophilic addition reaction with a nucleophile. If multiple substituents are attached to a phenyl ring, their activating/deactivating qualities govern mechanism of the reaction. The substituent ring with deactivating group precedes the reaction through benzyne intermediate formation. Methyl groups deactivate the ring towards nucleophilic addition reaction.
