Pyridine do not give good yield when undergoes electrophilic aromatic substitution, whereas pyridine N-oxide undergoes electrophilic aromatic substitution to give moderate yield is to be stated. Concept introduction: The electrophilic aromatic substitution reaction involves addition of electrophile (electron deficient species) on aromatic ring. These reactions occur in the presence of Lewis acid catalysts like AlCl 3 . To determine: Pyridine do not give good yield when undergoes electrophilic aromatic substitution, whereas pyridine N-oxide undergoes electrophilic aromatic substitution to give moderate yield.
