Question

Isomers which are non- superimposable mirror images are known as

• A. Epimers
• B. Enantiomers
• C. Mesomers
• D. Diastereomers

Answer 1

The correct option is B Enantiomers

Isomers which are non- superimposable mirror images are known as Enantiomers.
For a molecule to exhibit isomerism it should have chiral carbon or chiral axis or chiral plane.
Enantiomers rotate plane polarised in clockwise and anti-clockwise direction and exhibit optical activity.
Enantiomers are classified as l-isomer and d-isomer. l-isomer rotate light in anticlockwise direction and d-isomer rotates light in clockwise direction.
