If there are multiple functional groups of the same type, either prefixed or suffixed, the position numbers are ordered numerically (thus ethane-1,2-diol, not ethane-2,1-diol.) The N position indicator for amines and amides comes before "1", e.g., CH 3 CH(CH 3)CH 2 NH(CH 3) is N,2-dimethylpropanamine.
Because the S 2− anion has a subscript of 2 in the formula (giving a 4− charge), the compound must be balanced with a 4+ charge on the Pb cation (lead can form cations with a 4+ or a 2+ charge). Thus, the compound is made of one Pb 4+ cation to every two S 2− anions, the compound is balanced, and its name is written as lead(IV) sulfide .
In the ICZN, the system is also called binominal nomenclature, [1] "binomi'N'al" with an "N" before the "al", which is not a typographic error, meaning "two-name naming system". [ 2 ] The first part of the name – the generic name – identifies the genus to which the species belongs, whereas the second part – the specific name or specific ...
Compendium of Analytical Nomenclature: One extensive book on almost all nomenclature written (IUPAC nomenclature of organic chemistry and IUPAC nomenclature of inorganic chemistry) by IUPAC committee is the Compendium of Analytical Nomenclature (the "Orange Book"; 1st edition 1978). [53] This book was revised in 1987.
If it applies but no heteroatom is found in a chain, it is preferred over multiplicative nomenclature. Example: 3-phospha-2,5,7-trisilaoctane refers to CH 3-SiH 2-PH-CH 2-SiH 2-CH 2-SiH 2-CH 3. Skeletal replacement mainly replaces carbon with other atoms, or in the case of phane nomenclature, whole "superatom" rings.
Binomial nomenclature, as described here, is a system for naming species. Implicitly, it includes a system for naming genera, since the first part of the name of the species is a genus name. In a classification system based on ranks, there are also ways of naming ranks above the level of genus and below the level of species.

Nomenclature (UK: / n oʊ ˈ m ɛ ŋ k l ə tʃ ə, n ə-/, US: / ˈ n oʊ m ə n k l eɪ tʃ ər /) [1] [2] is a system of names or terms, or the rules for forming these terms in a particular field of arts or sciences. [3] (The theoretical field studying nomenclature is sometimes referred to as onymology or taxonymy [4]).
