N 2 O 3 is called nitrogen sesquioxide (sesqui-means 1 + 1 ⁄ 2). The main oxide of phosphorus is called phosphorus pentaoxide . It should actually be diphosphorus pentaoxide , but it is assumed that there are two phosphorus atoms (P 2 O 5 ), as they are needed in order to balance the oxidation numbers of the five oxygen atoms.
Meaning Origin language and etymology Example(s) -iasis: condition, formation, or presence of Latin -iasis, pathological condition or process; from Greek ἴασις (íasis), cure, repair, mend mydriasis: iatr(o)-of or pertaining to medicine or a physician (uncommon as a prefix but common as a suffix; see -iatry)

If a prefix form is required, "oxo-" is used (as for ketones), with the position number indicating the end of a chain: CHOCH 2 COOH is 3-oxopropanoic acid. If the carbon in the carbonyl group cannot be included in the attached chain (for instance in the case of cyclic aldehydes ), the prefix "formyl-" or the suffix "-carbaldehyde" is used: C 6 ...
The prefixes ortho, meta, and para are all derived from Greek, meaning correct, following, and beside, respectively. The relationship to the current meaning is perhaps not obvious. The ortho description was historically used to designate the original compound, and an isomer was often called the meta compound.
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
The prefix "spiro" followed by a Von-Baeyer descriptor describes in the nomenclature of organic compounds ring systems linked by only one common atom, the spiro atom. If several spiro atoms are present in the molecule, the prefix "spiro" is provided with a prefix ("dispiro", "trispiro", etc.) corresponding to the number of spiro atoms.
The general article about the organometallic chemistry of an element should be entitled "Organo[element] chemistry", e.g., organomercury chemistry, organopalladium chemistry, organozinc chemistry. The IUPAC definition of an "organometallic compound" includes boron, silicon, arsenic, and selenium, so this title guideline also applies to ...
