Illustrated Glossary of Organic Chemistry

Superimposable: The ability for an object to be placed over another object, usually in such a way that both will be visible. Often interchanged with broader term superposable (the ability for an object to be placed over another object; without the visibility restriction).


Molecular models of identical molecules are superimposable. Verify with your own molecular model kit.


Molecular models of unlike molecules (such as enantiomers) are not superimposable. Verify with your own molecular model kit.
