The correct statement(s) about the compound given below is are
Options
- Athe compound is optically active
- Bthe compound possesses centre of symmetry
- Cthe compound possesses plane of symmetry
- Dthe compound possesses axis of symmetry
Correct answer
A. the compound is optically active
Step-by-step solution
The compound does not possess centre of symmetry and plane of symmetry but possesses the proper axis of symmetry (C_n ) . A C_n axis of symmetry is an axis about which the molecule can be rotated by 360^ / n and thereby produce a molecule indistinguishable from the original molecule. From this face H (on right) and Cl (on left) are facing towards us and again on rotating at 180^ C -2 comes at C -1 place and again H (on right) and Cl (on left) are facing. We get an indistinguishable form on 180^ rotation, so it has
