Pyridine

pi-electron poor

Nitrogen lone pair (not involved in ring)

Basic and nucleophilic

HBA

Pyrrole (NH), Furan (O), Thiophene (S) - have heteroatoms (N, O, S)

Pyrrole -

pi-electron rich

Nitrogen lone pair involved in ring

Acidic due to NH - HBD

Imidazole

1 N lone pair in ring, 1 N lone pair not in ring

HBA and HBD

pos/neg charged shared equally between N’s, therefore:

Stronger base than pyridine

Stronger acid than pyrrole

FOUND IN HISTIDINE - acts as either acid or base - important in enzyme catalysis
