Solution

The correct option is D is non-super imposable on its mirror image
An organic compound is optically active if it is non-super imposable on its mirror image.
(Conditions for optical isomerism)

The compound should be asymmetric. It should not contain plane of symmetry (mirror image is not super imposable).

It should not contain any symmetry element such as the center of symmetry or axes of symmetry.

Hence the correct option is D.

Q. A compound whose molecule is superimposable on its mirror image despite containing chiral carbon atoms is:

Q. An organic compound having a carbon attached to four different groups is optically active. But, is the opposite also true? That is, do all optically active organic compounds have chiral carbons? Not necessarily. Presence or absence of chiral centre is not the sufficient criterion for optical activity. The ultimate criterion is the presence or absence of either plane or centre of symmetry. Two compounds which are non-superimposable mirror images of each other are called enantiomers. If a compound contains more than one chiral carbon, new words are required to describe the relationship between various stereoisomers of the compounds. Those words are diastereomers and mesomers.
