The traditional nomenclature is commonly used. Polymers are named according to one of the following  [Pg.8]

By the monomer s or hypothetical monomer s name, preceded by the word poly. For example, the polymer obtained by the polymerization of ethylene is called polyethylene. The polymer obtained by the polymerization of propylene is called polypropylene. Others such as polyvinyl chloride, polystyrene, and polyCmethyl methacrylate) are the polymers of vinyl chloride, styrene, and methyl methacrylate, respectively. The reaction of polyethylene and polyCvinyl chloride) is [Pg.8]


The nomenclature of boron hydride derivatives has been somewhat confusing and many inconsistencies exist in the Hterature. The stmctures of some reported boron hydride clusters are so compHcated that only a stmctural drawing or graph, often accompanied by explanatory text, is used to describe them. Traditional nomenclature systems often can be used to describe compounds unambiguously, but the resulting descriptions may be so long and unwieldy that they are of Htde use. The lUPAC (7) and the Chemical Abstract Service (8) have made recommendations, and nomenclature methods have now been developed that can adequately handle nearly all clusters compounds however, these methods have yet to be widely adopted. Eor the most part, nomenclature used in the original Hterature is retained herein. [Pg.227]

As discussed above, the important chemical property of acidity is highly solvent-dependent. but a traditional nomenclature emphasizes this property by using the word acid in the name. The aim of the systematic coordination nomenclature presented here is to describe a composition and a structure, not a chemical property. Consequently, a specialized word such as acid has no place in it. This is the hydrogen nomenclature [shown in Table 1-4). However, in recognition of current practice, the acid nomenclature is retained as an alternative. This is only partly systematic. [Pg.524]

In order to avoid further elements of confusion both the IUPAC and traditional nomenclatures will be outlined here. [Pg.76]

The traditional nomenclature used in the terpene field is at best an exacting exercise in memory. Most of the terpene names are derived from the genus or family names of the plants or from the essential oils from which the products were first isolated or in which they occur most abundantly. Many terpene names currently used, both for fundamental structures and especially for derivatives, give no clue as to the nature of the specific compounds or to the structural relationships which exist among several terpenes or between terpenes and similar organic compounds. [Pg.1]

The traditional nomenclature for salts of such metals is to use the suffix -ic for the higher ON and -ous for the lower, often using the Latin... [Pg.108]

In addition to the dimensionality of the model, one also must consider what one can called the dimensionality of the graph. All of the problems that are endemic to this phase of traditional nomenclature will be evaded in the nomenclature being proposed because the focus shall be strictly on the set of edges. The set of faces, in this system, has no significance. Consequently, the fact that Euler s Polyhedron Formula is applicable only to heuristically simple polytopes (of any dimension) is a problem that does NOT arise. [Pg.28]

As well as new properties of these molecules that have come to light with the discovery and nomenclating of the higher lullerenes and fulleranes, an extension that is unfathomable using traditional nomenclature, but is readily explained using beta bonds is next described when some of the carbon atoms are replaced by metal atoms in various of the smaller fullerenes. These molecules, which historically are not in the domain of... [Pg.151]

Traditional nomenclature for azo compounds nses the mnltiplicative prefix azo -N=N- e.g., Ph-N=N-Ph = azobenzene, Ph-N=N-CioH7 = 2-benzeneazonaphthalene or 2-phenylazonaphthalene. This is difficnlt to apply for more complex nnsymmetrical componnds, but remains in use. Another form fonnd in the older literature, especially for azo dyes, is naphthalene-2-azobenzene. [Pg.100]

It may be useful to recall that the somewhat confusing traditional nomenclature calls structures such as H2N-COO-R carbamates and Cl-CO-O-R chloroformates, while substitution at both N and O terminals gives urethanes. [Pg.192]

For compounds for which X-ray data have not yet been obtained, generic structural representations are shown. For these reagents, traditional nomenclature, such as uronium salts, has arbitrarily been retained. [Pg.285]

Isoleucine and threonine both have two chiral centers. According to official nomenclature the names L-isoleucine and L-threonine both designate only one optically active diastereoisomer. The mirror images are named D-isoleucine and o-threonine, whereas the diastereoisomers are named l-and D-alloisoleucine and l- and D-allothreonine. The configurations of L-isoleucine and L-threonine are shown in the formulas in Table I. The table also contains notation of the configuration at the two centers according to the R,S system and according to traditional nomenclature for amino acids (lUPAC-IUB, 1975). [Pg.235]

The molecules of amino acids have two functional groups with different properties, the basic amino group and the acidic carboxyl group. Because the amino group can be bound to different carbon atoms on the hydrocarbon chain, the names of these compounds are derived from the position of this functional group. However, for this class of compounds, the traditional nomenclature in which the C-atoms are labeled not by numbers, but by letters of the Greek alphabet is still in use. In addition, the letter a does not correspond to the carbon atom labeled with number 1, but to the atom with the number 2. In this nomenclature there are a, p, y amino acids, etc. [Pg.132]

Polymer compounds can be named according to the systematic nomenclature or the traditional nomenclature. [Pg.7]
