Pyrrole is a much weaker base than pyridine (see above). This is because the lone pair on the N atom is already involved in the aromatic array of p electrons. Protonation results in loss of aromaticity and is therefore unfavourable.
Why is pyridine more basic than pyrrole?
Pyridine consists of a stable conjugated system of 3 double bonds in the aromatic ring. Hence, the lone pair of electrons present on the nitrogen atom in pyridine has the ability to donate a hydrogen ion easily or a Lewis acid. Thus, pyridine is a stronger base than pyrrole.
What is the major difference between pyrrole and pyridine?
Terms in this set (12)
-Pyridine is electron deficient; the lone pairs on the nitrogen do not contribute to the aromatic ring. However, they make pyridine very basic. -Pyrrole is electron rich as the lone pair on the nitrogen contributes to the ring. - NO2 will be added to the ring in a SEar fashion.
