As a byproduct of historic improvement, there are diverse, unrelated structures of nomenclature for "inorganic chemistry", "organic chemistry", "polymer chemistry", "natural items chemistry", and so on. With every one new discovery within the laboratory, in addition to every one new theoretical notion for a chemical, the traces that typically have separated those "distinct" subsets of topic constantly develop extra blurred. This loss of uniformity in characterizing and naming chemical substances raises the verbal exchange problems among another way expert chemists, in addition to different scientists, and enormously impedes growth. With the set of recognized chemical compounds numbering over 42,000,000 (in Chemical Abstracts' facts base) and continuously becoming (about 2,000 new additions each day), the desirability for a unified process for naming all chemical compounds at the same time grows. furthermore, with the intention to meet the necessities of disparate teams of scientists, and of society normally, the identify assigned to a given chemical may still, not just uniquely describe that substance, but in addition can be part of a conveniently recognizable order for the full box. For those reasons, a topology-based "bi-parametric" method of nomenclature is herein proposed.- during this ebook, a brand new nomenclature procedure is proposed- the recent nomenclature is acceptable to a 3 dimensional global, and is internally constant- This nomenclature unifies ALL branches of chemistry, elimination the necessity for varied shortly present units of ideas"

One of these is that by labeling the nodes all equally, there is an increase in complexity of the nomenclature. Another layer of information needs to be addended in order to identify the atoms that comprise a given path. Furthermore, the names of the individual atoms are added only after all of the nodes of the graph have been named. Similarly, only after that, are the bond multiplicities indicated. For example, the same graph applies to both propane and to ethanol, as well as to dimethyl ether.

B) a predilection for five and six member rings that is so strong that it often overrides other, what nowadays is viewed as more important, considerations; namely, Dewar benzene is treated NOT as the fusion of two four member noncoplanar rings, but as an aberrant form of benzene and thus should be named exactly as though it were benzene. This is demonstrated in Note 9 and their description of what one might call "Dewar anthracene"* (Figure 8 is a copy of XII5 in [70]). This is followed by the assertion that what one has here is the traditional three fused hexagonal rings, rather than the four ring system of Figure 8.

This is seen in its examples of: 3-Penten-l-yne vs. l-Penten-4-yne, where the combined numbers 1,3 are selected as the priority numbering in the first of these names; however, since the same numbering 1,4 would result in the second of these compounds, the "-ene" is given preference. Moreover, in writing the IUPAC 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).
