Propanone and prop-2-en-1-ol are examples of functional isomers.
- Two or more compounds having the same molecular formula but different functional groups are called functional isomers and this phenomenon is termed functional group isomerism.
- In functional isomerism, the same sets of atoms are re-arranged in such a way that the two functional isomers have significantly different properties from each other due to their containing different functional groups. This means that they belong to different families of compounds.
