AP Chemistry Lab Brockport High School NY USA Organic Chemistry: Nomenclature and Isomers Mr Keefer Introduction Organic chemistry is the study of carbon-based molecules. The uniqueness of carbon allows for an enormous number of molecules, thus creating an inherent nomenclatural problem. The naming of organic molecules is carefully regulated by IUPAC, the International Union of Pure and Applied Chemistry. In general, most organic compounds have three names, prefix- parent-suffix. The logical approach to naming an organic compound follows these steps: 1. Find the parent hydrocarbon, usually the longest continuous carbon chain. 2. Number the atoms in the main chain. 3. Identify and number the substituents. 4. Write out the word as a single word, using hyphens and commas. This lab allows you to practice the rules of nomenclature and to introduce you to the concept of isomers, molecules with the same molecular formula, but different structures. Also, stereoisomerism is the isomerism of compounds having the same structural formula but different
