Nomenclature of Assemblies of Identical Units

Rule C-73. Derivatives of Assemblies of Identical Units

73.1 - When assemblies named in accordance with Rule C-72 contain substituents in the identical units in addition to principal groups, these substituents are named by use of prefixes. These prefixes are assigned the lowest locants available after priority has been given to the principal groups and the linking radical.

Examples to Rule C-73.1

Note: Assemblies of identical units linked by bi- or multi-valent radicals where the individual units contain different numbers of the principal group are named by the procedure given in Rule C-12.5.

See Recommendations'93 R-2.4.4 and R-1.2.8
