In this tutorial, Sal and Jay explain the concept of aromatic stabilization and show how to determine if a compound or an ion exhibits aromaticity. Knowledge of MO theory is assumed.
The aromaticity of benzene.
How the geometry of a molecule plays into aromaticity. Why cyclooctatetraene is not aromatic like benzene.
Aromaticity of the cyclopropenyl cation and antiaromaticity of cyclobutadiene.
Aromaticity of the cyclopentadienyl anion and cycloheptatrienyl cation.
Aromaticity of polycyclic compounds, such as naphthalene.
The aromaticity of heterocycles (rings containing one or more non-carbon atoms).
The aromaticity of pyrrole, imidazole, and thiophene.
