Resumo

CONCEPT AND QUANTITATIVE CRITERIA.In this paper the evolution of the concept of aromaticity is discussed.It considers not only historical aspects of the aromaticity concept but also the different criteria (theoretical and experimental) that have appeared to explain the properties of the aromatic compounds.The topics range from the isolation of benzene by Faraday (1825) until the modern criteria based on geometries, magnetic properties, resonance energy (RE), aromatic stabilization energy (ASE), topological analyses, and others.A chronological separation of issues concerning aromaticity was made, splitting the definitions before and after the appearance of the quantum chemistry.This work reviews the concept of aromaticity.
