During the last nomenclature session we were asked to name inorganic chemical structures and follow the english guidelines in order to name them appropriately. I believe this was a very good experience for all students as recognising and being able to translate in other languages chemical structures is a very important skill that needs to be developed. From my point view i found the english nomenclature very approachable as most of the chemicals are translated directly from the greek language. With application of the guidelines that we were given we managed to name them correctly and simultaneously learn the procedure. The procedure of naming compounds is just a set of rules.
Βefore doing this, a student have to figure out what kind of compound has.He also needs to be aware of the following nomenclature rules in order to name chemical structures.In the first place ionic compounds,which are the most commons in chemistry, consist of cations (positive ions) and anions (negative ions). The nomenclature, or naming, of ionic compounds is based on the names of the component ions. A Roman numeral in parentheses, followed by the name of the element, is used for elements that can form more than one positive ion. This is usually seen with metals.( Fe 2+ Iron
(II),Fe 3+ Iron (III),Cu + Copper (I),Cu 2+ Copper (II)).Although Roman numerals are used to denote the ionic charge of cations, It is still common to see and use the endings -ous or -ic. These endings are added to the Latin name of the element to represent the ions with lesser or greater charge, respectively.( ex.;Fe 2+ Ferrous,Fe 3+ Ferric,Cu + Cuprous,Cu 2+ Cupric).Secondly come the nonmetalnonmetal compounds .The first element in the formula is named first and full element name if used.(Ex.NO;Nitrogen oxide,SO2;Sulfur dioxide).The second element is named as though it were an anion.Also prefixes are used to denote the number of atoms present (mono, di, tri, tetra, penta, hexa, hepta, octa etc)(The prefix mono is never used for naming the first element).Thirdly we have the acids,known as electron acceptors(Lewis definition).In their compounds,if the anion does not contain oxygen,the acid is named with the prefix HYDRO- and the suffix –IC attached to the root name of the element.But if the anion contains oxygen,the acid is named from the root name of the central
element of the anio(or the anion name)with the suffix –IC or –OUS. Furthermore there is another group called oxyanions.We use the conclusion -ite for the one with smaller number of Oxygen atoms and - ate for the one with higher number of oxygen atoms.When there are more than two oxyanions in a series additional prefixes are used:Hypo- for the one with the fewest oxygens,Per- for the one with the most oxygens.The last category wich is hydrates,have a specfic number of water molecules in their chemical formulas. In the solid, these water molecules are part of the structure of the compound.The ionic compound (without the waters of hydration) is named first by using the rules for naming ionic compounds (ex.; Ba(OH)2•8H2O = "barium hydroxide"). In addition greek prefixes (mono, di, tri, tetra, penta, hexa, hepta, octa etc) are attached to the word "hydrate" to indicate the number of water molecules per formula unit for the compound (ex.; Ba(OH)2•8H2O; 8 water molecules = "octahydrate").(When the chemical formula for a hydrated ionic compound is written, the formula for the ionic compound is separated from the waters of hydration by a centered
"dot".).To sum up, the process that must be followed by a student in order to name a compound is: classify the compounds given,and then guided from the nomenclature rules above start naming the compounds.
