Moreover, in writing the lUPAC canonical name, the suffix "-ene" always precedes the "-yne". A more logical choice, incorporated into the proposed system, selects the longest contiguous, non-redundant path as the principal chain — without regard to any other parameters (such as maximizing the number of sites of bond unsaturation or of one degree of unsaturation over another). ^''''X1H) (6) H1C3C1C3C1C3C1C3C1H (7) and Returning the focus to Figure 12, the canonical name will, unlike in lUPAC nomenclature, have along its principal chain nine carbon plus two hydrogen atoms (This was indicated in the figure along the horizontal line).

Caution should be exercised that subscripts, superscripts and in-line numbers are clearly distinguished from one another. (2) Much of the tedium in (8) is introduced by naming all of the atoms in the molecule. Unlike other nomenclatures in which some atoms, namely the hydrogens, are inferred by default, no atoms are omitted in the proposed systemic nomenclature. , C and C respectively denote nonterminal CH and CH2 groups. Next observe that in the primary chain there is no distinction between C, C and C; therefore, it is often convenient to mix abbreviated and unabbreviated symbols.
