Study Notes
Isomerism
- Isomerism is a phenomenon in which two or more molecules have the same molecular formula but differ in their properties and structure.
- The term 'isomer' was coined by Swedish chemist Jöns Jakob Berzelius.
Structural Isomerism
- Another name for structural isomerism is constitutional isomerism.
- In structural isomers, atoms and functional groups are linked in different ways, resulting in different molecular structures.
- Different structural isomers have different IUPAC names because of their unique molecular structures, which are reflected in their IUPAC nomenclature.
