The difference between Stereoisomerism and Structural isomerism

When used as nouns, stereoisomerism means a form of isomerism in which atoms are arranged differently about a chiral centre (or centre of asymmetry). they exhibit optical activity, and in a molecule with a single chiral centre the two isomers (enantiomers) are mirror images of each other whereas in a molecule with multiple chiral centres the isomers (diastereoisomers) are not normally mirror images, whereas structural isomerism means a form of isomerism in which the same atoms are arranged in different orders, either having the same or different functional groups.
