Example text

An alternative representation, which does have more than just a modicum of merit, would be to present (9) above as: Fig. 21: lUPACName: TBPY-5 Systemic Name: (Xl)5:(l)^^'^'^"^'^'^'^'^^ In Chapter 6, a simplification that could be applied to (18) using spherical nomenclature is introduced; however, discussion of this alternate nomenclature shall be delayed until that time. 46 H2C6(C2C2)2C2C6C2C2H:\(4C)22H):\2H));'\4C2H:\2H)) (22) (22) counts the number of electrons shared by atoms, rather than on the number of bonds between them.

The elevated importance for selected atoms (designated as "central") in "inorganic chemistry". In other w^ords, the heuristics of relative importance determined the "clarity" of the defmition. Consequently, in order to formulate a unified nomenclature, one must, at the expense of discarding historical precedent, choose the same perspective for both subdomains. The milieu chosen is a graph theory based one. Harary [102] describes the term "bridge" as a single edge of a connected graph whose removal would disconnect that graph.

In the proposed system, bond orders greater than 0 and less than 1 are designated by the symbol a, bond orders greater than 1 and less than 2 by the symbol P, and non-integer bond orders greater than two by y . See footnote on page 20. 8. This wide range of deviation from integer value bonds was selected in order that single bonds continue to be used in formulating the nomenclature of peroxides, as well as having an equal interpretation in both alcohols and phenols. (Note that in hydrogen peroxide, as well as in alkyl peroxides, the bond between the oxygen atoms is much more easily broken than the bond between an oxygen atom and its hydrogen or carbon neighbor — both of which are still represented using single bonds.
