Nomenclature of special compounds

Unbranched assemblies that involve two or more identical hydrocarbon units joined via a single bond are named by placing a appropriate numerical prefix like bi for two, ter for three, quater for four, quinque for five etc. previous to the name of the repititive hydrocarbon unit. Starting from both of the ends, the carbon molecules of every repetitive hydrocarbon unit are numbered along with

unprimed and primed arabic numerals previously given as 1, 2, 3...., 1', 2', 3' ....., 1'', 2'', 3''..... etc. The points of attraction of the repititive hydrocarbon units are pointed out by placing the appropriate locants before the value.
