IUPAC states that, "As one of its major activities, IUPAC develops Recommendations to establish unambiguous, uniform, and consistent nomenclature and terminology for specific scientific fields, usually presented as: glossaries of terms for specific chemical disciplines; definitions of terms relating to a group of properties; nomenclature of chemical compounds and their classes; terminology ...
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.
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 ...

The hierarchy of scientific classification. Taxonomy mnemonics are used to memorize the scientific classification applied in taxonomy. They are usually constructed with a series of words that begin with the letters KPCOFGS, corresponding to the initials of the primary taxonomic ranks.
decacarbonyl-1κ 3 C,2κ 3 C,3κ 4 C-di-μ-hydrido-1:2κ 2 H;1:2κ 2 H-triangulo-(3 Os—Os), (Decacarbonyldihydridotriosmium). decacarbonyl-1κ 3 C,2κ 3 C,3κ 4 C shows that there are three carbonyl groups on two osmium atoms and four on the third. di-μ-hydrido-1:2κ 2 H;1:2κ 2 H specifies that the two hydride bridge between the osmium atom ...
