WBJEEThe complex showing a spin-only magnetic moment of \(2.82\) B.M. is \(\mathrm{Ni}(\mathrm{CO})_4\) \(\left[\mathrm{NiCl}_4\right]^{2-}\)...
The complex showing a spin-only magnetic moment of \(2.82\) B.M. is
Solution:
\(\mathrm{Ni}: 3 d^8 4 s^2 \quad \mathrm{Ni}^{2+}: 3 d^8\)
Since, \(\mathrm{Cl}\) is a weak field ligand, it doesn't cause pairing of electron.
Number of unpaired electrons, \(n=2\)
\(\)
\mu=\sqrt{n(n+2)}=\sqrt{2(2+2)} \mathrm{BM}=\sqrt{8} \mathrm{BM}=2.82 \mathrm{BM}
