Study Notes
Isomerism Concepts
- The term "constitutional isomer" was formerly used to describe the concept of structural isomerism.
Types of Isomerism
- Stereoisomerism is opposed to structural isomerism.
Structural Isomerism Subtypes
- Chain isomerism is a class of structural isomerism that involves only the rearrangement of atoms without altering the bonding scheme.
Classical Examples
- The ions [Cr(NH3)5Cl]SO4 and [Cr(NH3)5SO4]Cl are a classical example of structural isomerism.
Structural vs. Stereoisomerism
- Steroisomerism differs from structural isomerism in that it involves a change in the 3D arrangement of atoms, whereas structural isomerism involves a change in the bonding scheme.
