Study Notes
Systematic Identification of Organic Compounds
Why Systematic Identification?
- Necessary for effective communication among chemists
- Unambiguous identification of compounds
- Enables retrieval of information from databases and literature
IUPAC Nomenclature
- International Union of Pure and Applied Chemistry (IUPAC)
- Set of rules for naming organic compounds
- Unambiguous and consistent naming conventions
Rules for IUPAC Nomenclature
- Parent Compound: longest continuous chain of carbon atoms
- Substituents: atoms or groups attached to the parent chain
- Prefixes: indicate alkyl or functional groups attached to the parent chain
- Suffixes: indicate the functional group of the compound (e.g., -ol, -al, -one)
Steps for Systematic Identification
- Identify the parent chain: longest continuous chain of carbon atoms
- Identify substituents: alkyl or functional groups attached to the parent chain
- Number the carbon atoms: starting from the end of the parent chain closest to a substituent
- Assign prefixes and suffixes: according to IUPAC rules
- Write the complete name: combining the parent chain, substituents, and functional group
Examples
- 2-methylbutane
- Parent chain: butane
- Substituent: methyl
- Prefix: 2-
- Complete name: 2-methylbutane
- 3-chlorohexan-2-one
- Parent chain: hexane
- Substituent: chloro
- Prefix: 3-
- Suffix: -one
- Complete name: 3-chlorohexan-2-one
