Aromaticity

 

Aromaticity is a chemical property in which a conjugated ring of unsaturated bonds, lone pairs, or empty orbitals exhibit a stabilization stronger than would be expected by the stabilization of conjugation alone. It can also be considered a manifestation of cyclic delocalization and of resonance. An aromatic compound is one which has a ring structure around which electrons may move. That is, the electrons are not tied to a single atom or pair of atoms, they are shared by all the atoms around the ring. For this to be the case, certain conditions must be met:
