WebAromatic hydrocarbons are an integral part of motor fuels. The problem of reducing their concentration in the commercial blends is of a different nature for gasoline and diesel. Aromatics are desirable to meet the performance criteria of gasolines, where they provide the bulk of the octane rating, the fundamental quality for a spark-ignited engine.

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.
