Isomerism and Its Types

Isomerism: Definition and Significance

Definition: Isomerism refers to the existence of different compounds with the same molecular formula but distinct arrangements of atoms.

Significance: Understanding isomerism is essential for comprehending the intricacies of chemical structures and their corresponding properties.

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.
