Terpene Hydrocarbons

Rule A-75. Terpene Radicals

75.1 - Simple acyclic hydrocarbon terpene radicals are named and numbered according to Rule A-3.5. The trivial names geranyl, neryl, linalyl and phytyl [for (E)-(7R, 11R)-3,7,11,15-tetramethyl-2-hexadecenyl] are retained for the unsubstituted radicals.

75.2 - Radicals derived from menthane, pinane, thujane, carane, bornane, norcarane, norpinane, and norbornane are named in accordance with the principles set forth in Rules A-1.2 and A-11.4 except that the saturated radicals of pinane are named pinanyl, pinanylene, and pinanylidene. The numbering of the hydrocarbon is retained and the point or points of attachment, whether in the ring or side chain, are given numbers as low as is consistent with the fixed numbering of the hydrocarbon.

Examples to Rule A-75.2

75.3 - Radicals not named in Rules A-75.1 and A-75.2 are named as described in Rules A-11 and A-31.4.
