C-0.7. Nomenclature of Assemblies of Identical Units

For the purposes of this Subsection, "assemblies of identical units" comprise two or more identical components and are of two kinds: (a) those in which the components are joined by a double or single bond, not necessarily at the same position, with loss of a hydrogen atom from each component at each such bond; and (b) those in which the components are substitutively linked, not necessarily at the same position, by a symmetrical bivalent, tervalent, or quadrivalent radical. The resulting compounds may also be termed doubled, tripled, etc., compounds.

See Recommendations'93 R-2.4.4 and R-1.2.8
