4. a. (i) (ii) (iii) Pyridine is a six-membered aromatic heterocycle that undergoes nucleophilic aromatic substitution (NAS) but is not considered to be a good candidate for electrophilic aromatic substitution (EAS). What is the role of the aromatic molecule in EAS and NAS reactions? Explain why pyridine is poor at EAS nitration reactions? Explain, using resonance structures, why substitution occurs preferentially at the C-2 and C-4 positions rather than the C-3 position when pyridine undergoes NAS.
