An Introduction to Organic Chemistry
www.cnm.manchester.ac.ukAn Introduction to Organic Chemistry 82 Organic Chemistry Organic chemistry is the study of compounds containing carbon with the exception of simple compounds e.g. carbonates (CO 3 2-), carbon dioxide (CO 2) and carbon monoxide (CO). Nomenclature There are over 6 million known organic compounds. Nomenclature is therefore very important.

warwick.ac.ukNomenclature of Organic Compounds IUPAC has defined systematic rules for naming organic compounds. These will have already been covered in detail at A-level and will only be mentioned briefly here. The naming system (and the resulting names) can become very long with complex molecules, therefore this section will be restricted to simple compounds.
