Question

The criteria for optical isomerism are:

• A. the presence of at least one asymmetric carbon is essential
• B. the optical rotation is due to asymmetric carbon
• C. non-superimposible mirror image
• D. all of the above

Answer 1

Answer: (D)

all of the above

Optical isomerism is exhibited by at least one asymmetric carbon having four different atoms or groups attached to it. The enantiomers are optically active which are non-superimposable on their image. The optically active compound shows optical rotation towards the plane polarised light.
