What are positional isomers?

Isomers are molecules that have the same molecular formula but have a different arrangement of atoms in space.

• Positional isomers are constitutional isomers that have the same carbon skeleton and the same functional groups but differ from each other in the location of the functional groups on or in the carbon chain.
• In position isomerism, the basic carbon skeleton remains unchanged
