WebAromaticity is the property of a compound to have two types of orbitals – s-type and p-type. The s-type orbital is polar, while the p-type orbital is nonpolar. The ring current of an aromatic compound is the same as that of a diamagnetic compound, and thus, aromatic compounds can be distinguished by their ring current.
