Identify, from the following, the diamagnetic, tetrahedral complex
- A \(\left[\mathrm{Ni}(\mathrm{Cl})_4\right]^{2-}\)
- B \(\left[\mathrm{Co}\left(\mathrm{C}_2 \mathrm{O}_4\right)_3\right]^{3-}\)
- C \(\left[\mathrm{Ni}(\mathrm{CN})_4\right]^{2-}\)
- D \(\left[\mathrm{Ni}(\mathrm{CO})_4\right]\)
Answer & Solution
Correct Answer
(D) \(\left[\mathrm{Ni}(\mathrm{CO})_4\right]\)
Step-by-step Solution
Detailed explanation
(a) \(\mathrm{Ni}\) in \(\left[\mathrm{Ni}(\mathrm{Cl})_4\right]^{2-}\) exist as \(\mathrm{Ni}^{2+}\) ion. \(\because \quad \mathrm{C} \ell\) is a weak field ligand (high spin). It will not cause pairing of electrons. Hence, configuration of…
