  4. D \([Co(en) (NH_3)_2 Cl_2]^+\)
Verified Solution

Answer & Solution

Correct Answer

(C) \([Co(NH_3)_3Cl_3]\)

Step-by-step Solution

Detailed explanation

Optical isomerism is exhibited by only those complexes which lacks elements of symmetry. \(\left[\mathrm{Co}\left(\mathrm{NH}_{3}\right)_{3} \mathrm{Cl}_{3}\right]\) shows facial as well as meridional isomerism. But both the forms contain plane of symmetry. Thus, this complex…
