Question

The correct statement(s) about the compound given below is (are)
(2008)

• A. The compound is optically active
• B. The compound possesses centre of symmetry
• C. The compound possesses plane of symmetry
• D. The compound possesses axis of symmetry

Answer 1

Answer: (A), (D)

The compound possesses axis of symmetry

The given molecule although possesses neither centre of symmetry nor a plane of symmetry (hence optically active) but it has an axis of symmetry $\left(C_n\right).$

NOTE: A $C_n$ axis of symmetry is an axis about which the molecule can be rotated by ${360}^o/n$ to produce a molecule indistinguishable from the original molecule.
