Study Notes
Types of Isomerism
- Butane and isobutane are classical examples of structural isomerism.
- The term 'metamerism' was formerly used to describe structural isomerism.
Stereoisomerism vs Structural Isomerism
- Stereoisomerism differs from structural isomerism in that it involves a difference in spatial arrangement of atoms, while maintaining the same bond sequence.
- Structural isomerism, on the other hand, involves a difference in bond sequence, leading to distinct molecules.
Types of Isomerism
- Structural isomerism concerns the most radical differences in atomic bonding and arrangement.
Enantiomers
- Enantiomers represent non-superimposable mirror images of each other in terms of spatial arrangement.
