What is Chemical Nomenclature




What is Chemical NomenclatureDifferent sets of nomenclature rules are used depending on how compounds are classified, and the type of information to be conveyed. Rules exist based on source (origin) for organic (carbon containing), inorganic (non-living), biological (living) and miner al (geologic) compounds. 

Names may also reflect properties (such as acidic or basic behavior) and bonding, including ionic, covalent and coordination bonding. 2 It is possible for complicated substances to belong to more than one naming category; for example the biochemical substance in red blood cells commonly called hemoglobin has both or organic (protein) and inorganic (salt) components, and contains covalent, ionic and coordination bonding. 

The atomic theory of matter produced a symbolic representation for the molecules of substances in which element symbols (cf. Sec. 7.3) are subscripted to represent the number of atoms of each element.

Chemical Nomenclature Practice  

Chemical nomenclature practice: Confusion can arise in organic chemistry because of the variety of names that have been applied to compounds; common names, trade names and systematic names are prevalent. For example, a compound of formula, C 6 H 6 O has variously been known as phenol, carbolic acid, phenic acid, phenyl hydroxide, hydroxybenzene, phenylic acid and oxobenzene. 

To help eliminate the proliferation of many names for a compound, a systematic IUPAC naming system has been derived to uniquely name the several million organic different compounds based on considerations of their structure. 

This hand-out will address the naming of simple organic compounds and is by no means complete, for instance the compound, hexahydroazepinium-1-spiro-1-imidazo lidine-3-spiro-1-piperidinium dibromide may be regarded as being too complicated for this course. 

In general compounds are classified and named by consideration of: 

a) the number and types of atoms that are present,

b) the bond types in the molecule, and

c) the geometry of the molecule. 

Chemical Nomenclature Generator 

The nomenclature recommended and developed by IUPAC has highlighted the generation of unambiguous names which accord with the historical improvement of chemistry. In the progression of nomenclature a number of systems have emerged for that construction of chemical names; every system features its own set of rules and inherent logic.

Chemical nomenclature generator developed a set of rules with regard to naming the organic compounds. Underlying the IUPAC system of nomenclature with regard to organic compounds is a basic principle: Each various compound must have an unambiguous name. Therefore through a systematic pair of rules the IUPAC system gives different names for that more than 16 million known organic compounds and names could be devised for any one of millions of other compounds not yet been synthesized.
