R-220.127.116.11 By juxtaposition of component names. This method is most commonly used when the two components to be joined are: (a) a ring or a ring system; and (b) carbon chain (or chains) substituted by a principal characteristic group. In this method, both the principal characteristic group and the ring or ring system must terminate the chain; the rest of the structure attached to the chain, if any, is described by substituent prefixes, the location of which is indicated by Greek letter locants, , , etc., ( designating the atom next to the principal characteristic group).
R-18.104.22.168 By placing a multiplicative prefix [such as "bi-", "ter-", etc. (see R-0.1.4.3)], before the name of the corresponding parent hydride (see R-2.4.4)
