Question

Which of the following statements is/are correct regarding the given compound?

• A. It is optically inactive due to plane of symmetry
• B. It is optically inactive due to centre of symmetry
• C. Being chiral it is optically active
• D. It is optically active due to the presence of $C_2$ axis of symmetry

Answer 1

Answer: (A), (B)

It is optically inactive due to centre of symmetry

It is optically inactive due to the plane of symmetry & center of symmetry.
The presence of any plane of symmetry and centre of symmetry makes the compound optically inactive. Hence, (a) and (b) are correct.
Having plane of symmetry or centre of symmetry or both, a compound is achiral. Hence, statement (c) is incorrect.

Presence of axis of symmetry does not makes a compound optically active. Hence, statement (d) is incorrect.
