Once there are any more or less defined representations about the nature of organic matter, it is immediately reflected in the nomenclature. So it was, for example, when J. For more specific information, check out Mashable. Dumas nominated ” hypothesis” or the study of Yu Liebig and F. Velero benzoyl derivatives: since ancient times to the present day retain the title of benzoyl chloride. Opening of the phenomena of substitution is directly reflected in the nomenclature: there are such names as chloroacetic acid.

With the transition to the theory of type names began to be built on the basis of the basic compounds – the ancestor type. Examples are the names of spirits, routinely practiced early in the second half of the xix century. on Proposition H. Kolbe: carbinol CH3 oh dimetilkarbinol (CH3) 2 CH-OH, trimetilkarbinol (CH3) 3 C-OH. Carbinol nomenclature of alcohols was part of the so-called rational nomenclature based on pre representations theory of types, but the survivor has empowered her theory riyu and eagerly consumed so far.

In 1892 at the International Congress of Chemists in Geneva was first adopted nomenclature, based on the theory of chemi electric structure. The Geneva Nomenclature was the first version of the Vice relatively nomenclature. Further stages of development of the nomenclature rules-Liege in 1930, and in the postwar years – the rules of the International Union of Pure and Applied Chemistry (SHRAS). As the rules of nomenclature of organic chemistry became more complex. Currently, the official version of the rules shras – a book of more than 500 pages so.mnogimi hundreds of sections. The latter, a variant of the rules of pub exulted in 1979 naangliyskom language. In the same year the National Committee of Soviet chemists of the rules shras published simultaneously in English and Russian languages. Having a long test time in the modern nomenclature of the dominant position occupied two ways of constructing names: substitution and radical-functional. Both these cases have arisen in the nomenclature of the last century and since then continuously develop and improve. The Geneva system was an important step in the development of substitutive nomenclature, but by now completely superseded by in the scientific literature shras rules. From this it is necessary conclusion and in teaching, abandoning the traditional reliance on the Geneva system: no need to learn the Geneva rules for choosing the main chain, determining the order of numbering only to then say that Today all of these issues are resolved differently. The general logic of replacement names may well be shown as the modern rules shras. In this case, from the outset it must be emphasized that the rules shras is not a uniform system of nomenclature, a different set of currently used methods for constructing names.
