WebAn aromatic compound is characterized by its cyclic and planar structure and along with that conjugated system of the p orbitals which are found to be perpendicular to the molecule’s plane. This conjugation makes the molecule very stable. In comparison, a nonaromatic is found to be either non-cyclic or not in a planar form.
