Question

The correct order of the calculated spin-only magnetic moments of complexes (A) to (D) is
(A) $\mathrm{Ni}(\mathrm{CO})_4$ (B) $\left[\mathrm{Ni}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right] \mathrm{Cl}_2$
(C) $\mathrm{Na}_2\left[\mathrm{Ni}(\mathrm{CN})_4\right]$ (D) $\mathrm{PdCl}_2\left(\mathrm{PPh}_3\right)_2$

Select the correct option:

A

$(\mathrm{A}) \approx(\mathrm{C}) \approx(\mathrm{D})<(\mathrm{B})$

B

$(\mathrm{C}) \approx(\mathrm{D})<(\mathrm{B})<(\mathrm{A})$

C

$(\mathrm{A}) \approx(\mathrm{C})<(\mathrm{B}) \approx(\mathrm{D})$

D

$(\mathrm{C})<(\mathrm{D})<(\mathrm{B})<(\mathrm{A})$
