Aromatic compounds
Aromatic Compounds
Aromatic compounds, also known as arenes or aromatics, are chemical compounds that contain a ring of atoms with a particular arrangement of electrons. 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.
