Reference: OCR
Compounds with the same molecular formula but different structural formulae, meaning the atoms are joined in a different order or arrangement.
Isomers in which the connectivity changes, unlike stereoisomers where only the geometry does.
Compounds that differ in connectivity rather than only in arrangement in space.
