MCQ
Which of the following complex is homoleptic?
  • ✓
    $\left[\mathrm{Ni}(\mathrm{CN})_4\right]^{2-}$
  • B
    $\left[\mathrm{Ni}\left(\mathrm{NH}_3\right)_2 \mathrm{Cl}_2\right]$
  • C
    $\left[\mathrm{Fe}\left(\mathrm{NH}_3\right)_4 \mathrm{Cl}_2\right]^{+}$
  • D
    $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_4 \mathrm{Cl}_2\right]^{+}$
✓

Answer

Correct option: A.
$\left[\mathrm{Ni}(\mathrm{CN})_4\right]^{2-}$
a
In Homoleptic complex all the ligand attached with the central atom should be the same. Hence $\left[\mathrm{Ni}(\mathrm{CN})_4\right]^{2-}$ is a homoleptic complex.
