Isomerism: Definition and Significance
What is Isomerism? Isomerism refers to the existence of different compounds with the same molecular formula but distinct arrangements of atoms. Understanding isomerism is essential for comprehending the intricacies of chemical structures and their corresponding properties.
Â
Types of Isomerism
- Structural Isomerism
Molecules with the same molecular formula but different connectivity of atoms, leading to unique physical and chemical properties.
- Stereoisomerism
Molecules with the same connectivity of atoms but different spatial arrangements, resulting in differences in optical and geometric properties.
- Geometric Isomerism
A subset of stereoisomerism involving compounds with restricted rotation, leading to cis-trans or E-Z isomers.
