class of organical compounds whose structure includes at least one cycle of partially unsaturated bonds with delocalized pi electrons all around
2D model of a benzene molecule. The carbon atoms joined into a "ring" with conjugated double-bonds defines benzene as "aromatic". Aromatic compounds or arenes are organic compounds "with a chemistry typified by benzene" and "cyclically conjugated." The word "aromatic" originates from the past grouping of molecules based on odor, before their general chemical properties were understood. The current definition of aromatic compounds does not have any relation to their odor. Aromatic compounds are now defined as cyclic compounds satisfying Hückel's rule. Aromatic compounds have the following general properties:
Typically unreactive
