Heteroaromatic compounds, i.e., compounds containing heteroatoms partially or fully instead of the carbon atom of the aromatic hydrocarbon, have been actively studied for a long time from the viewpoints of characteristic differences from aromatic hydrocarbons and the applicable scope of aromaticity. 8.4 Aromatic Compounds: Benzene. 8.2 Properties of Alkenes. For example, benzene is more stable than 1,3,5-hexatriene. The compound is cyclic, but it does not have a benzene ring; it is not aromatic.
