When a metal has a variable oxidation number, its name is followed by the oxidation number written in Roman numeral enclosed in parenthesis. The old method used the stem of the Latin name and the suffixes ‘ous’ and ‘ic’ for the lower and higher states, respectively.Examples: ...
Out-of-date nomenclature used the suffixes –icand –ousto designate metals with higher and lower charges, respectively: Iron(III) chloride, FeCl3, was previously called ferric chloride, and iron(II) chloride, FeCl2, was known as ferrous chloride. Though this naming convention has been largely...

Prefixes or part of them, depending on the kind of prefix, can be joined to the name component they are often followed by a hyphen, as in ‘tert-butyl’, but not necessarily so, as in ‘isopropyl’. Hyp-2.3 Suffixes Suffixes in chemical names always indicate a functional group, usually...
Fatty Acid Definition:A fatty acid is a carboxylic acid with a long side chain of hydrocarbons. Most fatty acids contain an even number of carbon atoms in the hydrocarbon chain and follow the general molecular formula of CH3(CH2)xCOOH where x is the number of carbon atoms in the hydrocarbon...

Thus, FeCl2 is iron(II) chloride and FeCl3 is iron(III) chloride. Some compounds contain polyatomic ions; the names of common polyatomic ions should be memorized. Molecular compounds can form compounds with different ratios of their elements, so prefixes are used to specify the numbers of atoms...
