Study Notes
IUPAC Nomenclature
- Deviations from the longest chain of carbons are indicated by assigning a number to the parent chain and numbering the substituents accordingly
- The purpose of the IUPAC system of nomenclature is to provide a standardized method of naming organic compounds, ensuring clarity and precision in communication among chemists
- The fundamental principle of IUPAC nomenclature is based on the concept of parent structure and substituents, where a molecule is divided into a main parent structure and smaller substituent groups attached to it
Hydrocarbons
- Cycloalkanes are a type of saturated hydrocarbon that contains a ring of carbons, with the general formula CnH2n
- Alkanes are a type of saturated hydrocarbon that contains a chain of carbons, with the general formula CnH2n+2
