Question

Select the correct statement about A and B

• A. A is optically active
• B. B is optically active
• C. Both (a) and (b)
• D. None of the above

Answer 1

The correct option is A A is optically active

In A, free rotation about single bond is possible and each ring has a vertical plane of symmetry. Hence it does not show optical esomers.

The diphenyl is sterically hindered because of bulky ortho substituents, therefore phenyl cannot be coplanar and every barrier for rotation is very high for interconversion.
