Consider the complex ions, trans- Co(en)2Cl2*(A) and cis-Co(en)2Cl2+(B). The correct statement regarding them is :
  1. both (A) and (B) cannot be optically active.
  2. (A) can be optically active, but (B) cannot be optically active.
  3. both (A) and (B) can be optically active.
  4. (A) cannot be optically active, but (B) can be optically active.

Solution

  

Have Plane of symmetry so will be optically inactive.

Trans-[Co(en) Cl22+

  

cis-[Co(en) Cl22+→ is optically active without plane of symmetry.
