A) \[M{{n}^{2+}}\]
B) \[N{{i}^{2}}^{+}\]
C) \[C{{o}^{2+}}\]
D) \[F{{e}^{2}}^{+}\]
Correct Answer: C
Solution :
\[_{27}C{{o}^{+2}}=[Ar]\,3{{d}^{7}}\,4s{}^\circ \,\text{4p}{}^\circ \] No. of unpaired \[{{e}^{-}}=3\] (For weak field ligand) \[_{27}C{{o}^{+2}}=[Ar]\,3{{d}^{7}}\,4{{p}^{0}}\] For strong field ligand No. of unpaired \[{{e}^{-}}=1\]You need to login to perform this action.
