The proper name of a compound is the simplest systematic name which can unambiguously specify the compound being spoken of. Chemical elements, which are the simplest forms into which materials can be resolved by chemical means, react with each other to yield chemical compounds containing various proportions of two or more elements. Therefore the names of compounds should be derived from the names of the elements of which they are composed. These three principles were originally fundamental to all chemical nomenclature. Later, as chemistry evolved into the two traditional areas of organic and inorganic chemistry, the third principle was retained only for inorganic compounds, for the following reasons.
Organic chemistry is the study of the covalent compounds based on the elements carbon and hydrogen.
Inorganic compounds, however, are still named according to the principle that the name of an inorganic compound is derived from the names of the chemical elements which make up that compound . There are many more different types of inorganic compounds, even though the number of known organic compounds is very much greater than the number of known inorganic compounds. It would be false to give you the impression that there is one and only one rigid system of naming either organic or inorganic compounds. Since names are derived from an understanding of the nature and the structure of the compounds, nomenclature systems used must allow for improvements in understanding and also in names. On the other hand, nomenclature systems cannot permit excessive changes in names.
