Which of the following statements are correct?
i. \(\left[\mathrm{Mn}(\mathrm{CN})_6\right]^{3-},\left[\mathrm{MnCl}_6\right]^{3-}\) both are paramagnetic
ii. Both \(\left[\mathrm{NiCl}_4\right]^{2-},\left[\mathrm{Ni}(\mathrm{CO})_4\right]\) are tetrahedral and diamagnetic
iii. \(\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_6\right]^{3+}\) is inner orbital complex, but \(\left[\mathrm{Ni}\left(\mathrm{NH}_3\right)_6\right]^{2+}\) is outer orbital complex
- A i, ii only
- B i, iii only
- C ii, iii only
- D i, ii, iii
Answer & Solution
Correct Answer
(B) i, iii only
Step-by-step Solution
Detailed explanation
\(\left[\mathrm{NiCl}_4\right]^{2-}\) has \(\mathrm{Ni}^{2+}\) that has the configuration \([\mathrm{Ar}] 3 \mathrm{~d}^8\). Since \(\mathrm{Cl}^{-}\)is a weak-field ligand, the configuration of the complex will be:- \(\left[\mathrm{NiCl}_4\right]^{2-}=\) Thus, it is a…
