mAn '''aromatic ring''' is a [[hydrocarbon]], such as [[benzene]], that has a low [[hydrogen]] to [[carbon]] ratio. As in the case of benzene (formula C<sub>6</sub>H<sub>6</sub>), the carbon atoms form a hexagonal ring, with each carbon atom bonded in series at each point of the hexagon. Because of [[double bond|double bonding]], each carbon atom can bond to only one hydrogen.
