Which one of the following complexes is not expected to exhibit isomerism?

Options

  1. A\left[\mathrm{Ni}\left(\mathrm{NH}_3\right)_4\left(\mathrm{H}_2 \mathrm{O}\right)_2\right]^{2+}
  2. B[Pt(NH3)2Cl2]\left[\mathrm{Pt}\left(\mathrm{NH}_3\right)_2 \mathrm{Cl}_2\right]
  3. C[Ni(NH3)2Cl2]\left[\mathrm{Ni}\left(\mathrm{NH}_3\right)_2 \mathrm{Cl}_2\right]
  4. D[Ni(en)3]2+\left[\mathrm{Ni}(\mathrm{en})_3\right]^{2+}

Correct answer

C. [Ni(NH3)2Cl2]\left[\mathrm{Ni}\left(\mathrm{NH}_3\right)_2 \mathrm{Cl}_2\right]

Step-by-step solution

\left[\mathrm{Ni}\left(\mathrm{NH}_3\right)_2 \mathrm{Cl}_2\right] has tetrahedral geometry and thus, does not exhibit isomerism due to presence of symmetry elements.
