A) \[{{d}^{5}}\](in strong ligand field)
B) \[{{d}^{3}}\](in weak as well as in strong fields)
C) \[{{d}^{4}}\](in weak ligand fields)
D) \[{{d}^{4}}\](in strong ligand fields)
Correct Answer: D
Solution :
\[{{d}^{5}}-\]strong ligand field |
\[\mu =\sqrt{n(n+2)}=\sqrt{3}=1.73BM\] |
\[{{d}^{3}}-\]on week as well as in strong field |
\[\mu =\sqrt{3(5)}=\sqrt{15}=3.87B.M.\] |
\[{{d}^{4}}-\]in week ligand field |
\[\mu =\sqrt{4(4+2)}=\sqrt{24}=4.89\] |
\[{{d}^{4}}-\] in strong ligand field |
\[\mu =\sqrt{2(4)}=\sqrt{8}=2.82.\] |
