What is structural isomerism? Give example.
Structural isomerism is a type of isomerism in which two or more molecules have the same molecular formula but different structural formulas. In other words, structural isomers have the same number of atoms of each element but differ in their bonding arrangements, leading to different physical and chemical properties.
Examples of structural isomers include:
- Butane and isobutane (C4H10)
- Ethanol and dimethyl ether (C2H6O)
