Arene
Definition
A generic name assigned to aromatic hydrocarbons, cyclo-unsaturated organic compounds containing at least one stable benzene nucleus or ring within their molecular structure. In a structural sense, arenes feature a completely delocalized pi-pi electronic conjugation, responsible for their exceptional chemical stability, specific electrophilic substitution properties, and pronounced aromatic character.
