    Whether or not a compound is aromatic may be determined by the so-called Frost circle - a simple method used to estimate the relative π orbital energies of both planar and cyclic compounds with an uninterrupted π electron system: To begin with, the structure of the cyclic compound is placed inside a circle with one of its vertices pointing downwards. A short horizontal line is then added to each of the molecular structure's vertices, along with a horizontal dashed line that runs right through the circle's and molecule's center.

    According to Hückel's rule, an aromatic compound must have (4n + 2) π electrons that form an uninterrupted π electron cloud. In addition, it must be planar and cyclic. If the compound is not planar and cyclic then it is also not aromatic. The bonding π MO (molecular orbitals) of an aromatic compound are fully occupied, while the antibonding and non-bonding π MO are fully unoccupied. Whether or not a compound is aromatic may be determined by the so-called Frost circle - a simple method used to estimate the relative π orbital energies of both planar and cyclic compounds with an uninterrupted π electron system
