The iupac nomenclature system is a set of logical rules devised and used by organic chemists to circumvent problems caused by arbitrary nomenclature.

This work, titled méthode de nomenclature chimique (method of chemical nomenclature, 1787), introduced a new system which was tied inextricably to lavoisier's new oxygen theory of chemistry. The classical elements of earth, air, fire, and water were discarded, and instead some 55 substances which could not be decomposed into simpler substances.
They also added a detailed list of rules for naming an element. Even back in the 1700s, chemists recognised the need for a standardised naming system. By 1919, iupac was founded to try to bring some rigour to the naming of elements.

Long before chemists knew the formulas for chemical compounds, they developed a system of nomenclature that gave each compound a unique name. Today we often use chemical formulas, such as nacl, c 12 h 22 o 11, and co(nh 3) 6 (clo 4) 3, to describe chemical compounds.
Naming compounds that involve transition metal cations necessitates that use of the stock system. To simply name this compound iron chloride would be incomplete because iron is capable of forming two ions with different charges.
This observation may lead researchers to a revised definition of supertasters, to mean those people with heightened taste sensations for all tastes, not only the bitterness of one class of chemical compounds. The authors use new nomenclature to introduce this distinction, referring to supertasters defined by the prop rating as pst (prop.
Thus, the nomenclature of alkanes, for instance, would differ based upon the iupac system. Let us look at the iupac names of alkane, alkene and alkyne along with the rules for naming such compounds. The basic structure of the nomenclature system formulated by iupac rests on two factors.
In order to name organic compounds you must first memorize a few basic names. These names are listed within the discussion of naming alkanes. In general, the base part of the name reflects the number of carbons in what you have assigned to be the parent chain.

Nomenclature for these compounds is trivial; the cation is named first, followed by the anion. If the anion is a single element, the suffix ide is added to the root name of the element. When you are constructing names for ionic compounds, you do not use “multipliers” to indicate how many cations or anions are present in the compound.
