The divergence of chemical naming is associated with three chronological eras: (1) the pre-historic era, almost all languages have their own words for "water", "iron" and "gold"; (2) the traditional era following the systematization of chemistry by Antoine Lavoisier around the 1780s, including names like "acetic acid", "butyric acid" and the periodic table; and finally (3 . I would input data from chemist for the purpose of publishing research for the worlds leader in chemical information. It should conform as closely as possible to one of the following two nomenclature systems: the rules established by the International Union of Pure and Applied Chemistry (IUPAC), or the rules used in the Chemical Abstracts Index Guide.

Nomenclature exercise (Chemical abstracts) Hello guys. Chemical nomenclature is at least as old as the pseudoscience of alchemy, which was able to recognise a limited number of reproducible materials. Chemical compounds are named for a variety of reasons such as for databases, publications, patents, and legal situations. This book is devoted to provide a coherent picture how the trivial and systematic names shall be used and how the current IUPAC rules help to reconcile the conflicting demands. Posted by 7 years ago.
