Arenes The aromatic hydrocarbons also have the name arenes. They contain in their molecule one or more cycles made up from 6 carbon atoms. When the molecule is formed out of a single cycle‚ the hydrocarbons are mono nucleuses; when the molecule contains more than one cycle‚ the hydrocarbons are poly nucleuses. The simplest aromatic hydrocarbon‚ benzene‚ is compound out of just one such cycle; its formula is C6H6. The representation of benzene through a cycle of 6 carbon atoms with 3 double bounds
