Would pyridine be faster in a nucleophile aromatic or an electrophilic aromatic reaction? Why?
Homework Answers
In organic reactions, pyridine behaves both as a tertiary amine, undergoing protonation, alkylation, acylation, and N-oxidation at the nitrogen atom, and as an aromatic compound, undergoing nucleophilic substitutions.
Because of the electronegative nitrogen in the pyridine ring, the molecule is relatively electron deficient. It, therefore, enters less readily electrophilic aromatic substitution reactions, which are characteristic of benzene derivatives.

Nitration of phenols is a classic example of an electrophilic aromatic substitution reaction. a) Why does the nitration of phenol (hydroxybenzene) proceed only in the ortho- and para-positions on the ring? b) Draw the resonance structures that highlight the ortho- and para-directing nature of hydroxy substituents. Make sure to include the structures that showcase the movement of the charges in the ring.
