Structural Isomerism
Structural isomerism refers to the phenomenon where compounds with the same molecular formula have different structural arrangements of their atoms. This difference in structure leads to distinct physical and chemical properties.
Constitutional isomers, a type of structural isomer, are compounds that have the same molecular formula but differ in the way their atoms are connected. For example, butane (C4H10) has two constitutional isomers: n-butane and isobutane.
Bond-Line Structures
Bond-line structures are simplified representations of molecules that use lines to represent bonds and circles or dots to represent carbon atoms. These structures provide a clear and concise way to visualize the connectivity of atoms within a molecule.
- Start by drawing a circle or dot for each carbon atom in the molecule.
- Connect the carbon atoms with lines to represent the bonds between them.
- Add hydrogen atoms to each carbon atom to satisfy its valency.
- Remove any unnecessary lines or circles.
