The most common aromatic molecule is benzene (
Pyrrole, furan, and thiophene are other aromatic compounds with
The heteroatoms each contribute two electrons to the π system.
However, the resonance stabilization in thiophene (122 kJ/mol) is less than that in benzene (152 kJ/mol), because
But, because thiophene is aromatic, it does not have the properties of ordinary thioethers.
