It is a generally accepted standard that editors should attempt to follow, though it is best treated with common sense, and occasional exceptions may apply. Generally, article naming should give priority to what the majority of English speakers would most easily recognize, with a reasonable minimum of ambiguity, while at the same time making linking to those articles easy and second nature. IUPAC recommends the use of non-systematic names for some organic compounds, and these recommendations should be followed in article titles. Traditionally, the names of three elements have been spelled differently in different parts of the English speaking world. These spellings should be used in all chemistry-related articles on English Wikipedia, even if they conflict with the other national spelling varieties used in the article. In former versions of the IUPAC recommendations, names were written with a capital initial letter. This practice has been abandoned in later publications.
The names of chemical compounds and chemical elements when written out, are common nouns in English, rather than proper nouns. Likewise, the names of chemical compounds are considered common nouns which are capitalized at the beginning of a sentence or title, but not elsewhere. N-, O-, α-, β-, γ-, etc. A redirect from the uncapitalized version should be created to simplify linking from other articles. Both numerical and non-numerical prefixes are followed by a hyphen. No hyphens or italics are used in these cases.
Note that this is an exception to the usual English style for parentheses. Stock nomenclature should only be used for ionic compounds. IUPAC convention for chemical elements, and is not changed when the isotope is written out. You may use a nuclide template. Deuterium and tritium may be labelled “D”, “2D”, or “2H” and so on. From Wikipedia:Deletion policy: “Don’t worry, redirects are cheap.
Even with the best will in the world, no set of guidelines can cover every case. IUPAC or the other rules suggest. For articles about functional groups, the singular class name from the Glossary of Class Names is usually used, e. Where the group is not considered to be functional, e. The general article about the organometallic chemistry of an element should be entitled “Organo___ chemistry”, e.

Are expressed as separate sub, the situation is similar to that with the Internet DNS lookup which resolves host name to the IP address.

Fundamental Toxicology is a textbook that proposes a curriculum for toxicology courses. IUPAC is governed by several committees that all have different responsibilities. Though it is best treated with common sense, but structures are not unique or convenient for computers. Case letters as most if not all search engines may not differentiate between upper; it would try to recognize tetrahedral stereo expressed through wedge bonds.
IUPAC definition of an organometallic compound. Depending on the metallic element, it may well be appropriate to have additional articles covering specific compounds or groups of compounds, or specific reactions.

IUPAC was established in 1919 as the successor of the International Congress of Applied Chemistry for the advancement of chemistry. IUPAC is best known for its works standardizing nomenclature in chemistry and other fields of science, but IUPAC has publications in many fields including chemistry, biology and physics.
