WebIn chemistry, aromaticity is a chemical property ... Since the most common aromatic compounds are derivatives of benzene (an aromatic hydrocarbon common in petroleum and its distillates), the word aromatic occasionally refers informally to benzene derivatives, and so it was first defined. Nevertheless, many non-benzene aromatic compounds exist. WebIn the 1800s, the Kekulé structure was suggested for benzene with a six membered cyclic ring of carbon atoms, with alternate single and double bonds. The technical name of this structure is cyclohexa-1,3,5-triene. This structure was found to be incorrect due to a number of unexpected physical and chemical properties. Low Reactivity
