Question

Which of the structures given below are chiral ?

• A. I, II, III and V
• B. I, III and V
• C. II, III
• D. I, II

Answer 1

The correct option is A I, II, III and V

Objects having non-superimposable mirror images are known as chiral objects.

Similarly, compounds having non-superimposable mirror images are known as chiral compounds.

Generally, chiral compounds have a chiral carbon and lacks plane and centre of symmetry.

Chiral compounds are also optically active.

Among the given compounds, (IV) has plane of symmetry so it does not show chirality even if it has a chiral carbon.

All other compounds has chiral carbons and have non-superimposible mirror images and lacks both plane and centre of symmetry.



Hence, (a) is correct.
