They are composed of more than one aromatic ring.

However, no alkenes outside of the initial aromatic ring are created.

This process goes through an excited state energy minimum where the aromatic rings lie at 90 to each other.

It is also important to know that 10-35% of the carbon present forms aromatic rings.

Many chemical compounds are aromatic rings with other functional groups attached.

These color changes are caused by nitrated aromatic rings in the protein.

The term can also be extended to substituents on aromatic rings.

The His292 binds to the hydroxyl group of the aromatic ring.

The electrons are taken up by the aromatic ring, one at a time.

Many chemical compounds are aromatic rings with other things attached.
