As the name suggests, cyclic structures form rings, as opposed to branching chain structures. Aside from a ring shape, aromaticity involves a continuous pi system. Aromatic compounds, also known as "mono- and polycyclic aromatic hydrocarbons", are organic compounds containing one or more aromatic rings. The word "aromatic" originates from the past grouping of molecules based on smell, before their general chemical properties are understood. The current definition of aromatic compounds does not have any relation with their smell. fish with tomatoes recipe
