    Definition any of a large class of unsaturated chemical compounds characterized by one or more planar rings of atoms joined by covalent bonds [IATE:1552759 ] of two different kinds Reference COM-EN, based on: Encyclopaedia Britannica. Aromatic compoundchemical compound. Francis A. Carey, https://www.britannica.com/science/aromatic-compound [13.2.2018]
    Comment The term 'aromatic' was assigned before the physical mechanism determining aromaticity was discovered, and was derived from the fact that many of the compounds have a sweet scent. The configuration of six carbon atoms in aromatic compounds is known as a benzene ring, after the simplest possible such hydrocarbon, benzene [ IATE:1566036 ]. Aromatic hydrocarbons can be monocyclic (MAH) or polycyclic (PAH).
