Study Notes
Structural Isomerism
- Structural isomerism occurs when molecules have the same molecular formula but differ in the way their atoms are connected.
- It involves the arrangement of atoms in a molecule, resulting in different molecular structures.
- Structural isomerism is a type of isomerism that involves a difference in the connectivity of atoms.
Examples of Structural Isomerism
- Butane (CH₃CH₂CH₂CH₃) and 2-methylpropane (CH₃CH(CH₃)CH₃) are examples of structural isomers, as they have the same molecular formula (C₄H₁₀) but differ in their atomic connectivity.
Characteristics of Structural Isomers
- Structural isomers have the same molecular formula but differ in their molecular structure.
- They are distinguished from each other by their different atomic connectivity.
- Structural isomerism is a phenomenon that illustrates the concept of molecular chaos, where a single molecular formula can give rise to multiple molecular structures.
