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.
