What is chemistry nomenclature?

A level and university chemistry students are introduced to a scheme of nomenclature that enables the systematic and unambiguous naming of organic chemical compounds. This is especially true in the field of organic chemistry, which features many types of isomerism. Given the vast number of chemical compounds, it is essential that researchers use the one scheme of naming and classification.

A few answers here should walk through the process of naming an organic compound, which includes determining the longest organic chain and naming functional groups based on predetermined priorities. This is paralleled with the so-called trivial names for common organic compounds, which are hallowed by usage and which most chemists would identify.

Chemistry nomenclature refers to the systematic naming of chemical compounds according to specific rules and conventions established by the International Union of Pure and Applied Chemistry (IUPAC).
