Aromatic Examples

The definition of aromaticity? To be aromatic, a portion of a molecule must have all of the following criteria:

• Cyclic
• At least 1 p orbital on each atom
• Planar (with continuous overlap between p orbitals)
• 4n + 2 electrons total in the pi system, where n is any whole number (0, 1, 2, etc.). This mean that common allowable values for the total number of electrons are 2, 6, 10 and so forth.
