Until the nineteenth century, the names of organic compounds were given arbitrarily, only remembering their origin or any of their characteristics.
Thus, for example, H - COOH was called formic acid because it was found in certain ants.
As the number of organic compounds increased, the situation became so complicated that the chemists gathered at the Geneva International Congress in 1892 decided to start rationalizing the organic nomenclature.
After several international meetings, the so-called IUPAC (International Union of Pure at Applied Chemistry) nomenclature emerged.
The IUPAC nomenclature is made up of numerous rules, with the aim of giving quite logical names to organic compounds, so that:
- each compound has a different name that distinguishes it from all others;
- given the structural formula of a compound, it is possible to elaborate its name, and vice versa.
