The geometries of \(\left[\mathrm{Ni}(\mathrm{CO})_4\right],\left[\mathrm{PtCl}_4\right]^{2-}\) and \(\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_6\right]^{3+}\) respectively are
- A tetrahedral, tetrahedral and octahedral
- B tetrahedral, square planar and square pyramidal
- C square planar, square planar and octahedral
- D tetrahedral, square planar and octahedral
Answer & Solution
Correct Answer
(D) tetrahedral, square planar and octahedral
Step-by-step Solution
Detailed explanation
\(\left[\mathrm{Ni}(\mathrm{CO})_4\right]\) Ground state electronic configuration \(=3 d^8 4 s^2\) \(\mathrm{CO}\) is strong field ligand, so it pushes \(10 e^{-}\)to \(3 d\)-orbital. The hybridisation of \(\left[\mathrm{Ni}(\mathrm{CO})_4\right]\) is \(s p^3\) and geometry is…
