There are two types of isomerism i.e. structural isomerism and stereoisomerism. The two main types of stereoisomerism are: Diastereomerism (including 'cis-trans isomerism' and Optical Isomerism). Each non-superimposable mirror image structure is called a/an:
Correct answer: C. Enantiomer
- A. Metamer
- B. Elastomer
- C. Enantiomer
- D. Tautomer
Explanation
Optical isomers are pairs of molecules that are non-superimposable mirror images of each other. Each member of such a pair is called an enantiomer. Enantiomers have identical physical properties except for their interaction with plane-polarized light.

About Fundamental Principles of Organic Chemistry
Organic chemistry begins with carbon compounds classified by carbon skeleton, saturation and functional group. Work includes identifying groups such as hydroxyl, carbonyl, carboxyl and amino, applying basic nomenclature, and distinguishing structural, geometric and optical isomers, where the same molecular formula does not necessarily mean the same structure or properties.
