Nomenclature of Hydrocarbons

Nomenclature: naming of compounds

There are three tips of nomenclature: trivial, rational and IUPAC (systematic)

Trivial nomenclature uses parent names, that were formed historically.

e.g.

acetic acid, tartaric acid, wood alcohol.

Accoding to the rational system of nomenclature, organic compounds are the derivatives of the simplest member of homologous series hydrocarbons: alkanes – methane, alkenes – ethane (ethylene), alkynes – ethyne (acetylene)

Rational system of nomenclature is used not often (for naming of compounds with simple structure).

IUPAC system of nomenclature has the largest use

The formal system of nomenclature is proposed by the International Union of Pure and Applied Chemistry (IUPAC)

Fundamental principle of IUPAC system of nomenclature:
Each different compound should have a different name.
