the graphic representation of the structure of benzene as a hexagon with a carbon atom at each of its points. Each carbon atom is united with an atom of hydrogen, one or more of which may be replaced to form benzene derivatives.
Also called benzene nucleus.

the hexagonal ring of bonded carbon atoms in the benzene molecule or its derivatives Also called benzene nucleus See also Kekulé formula
A hexagonal arrangement of six carbon atoms, each atom bonded to its adjacent atoms by a single covalent bond, and by an unusual ring bond of electrons shared by all six carbon atoms. The benzene ring is a basic component of many organic compounds, especially the aromatic hydrocarbons. In benzene itself, each carbon atom is also bonded to a hydrogen atom; in derivatives of benzene, one or more of the hydrogen atoms is replaced by other atoms or groups of atoms.
- Benzene series
a series of aromatic hydrocarbons derived from benzene by replacing one or more of the hydrogen atoms with one or more methyl groups. The first three members are benzene, toluene, and xylene.
