In which of the following complexes of the Co (atomic no. $$=27$$), will the magnitude of $$\Delta_o$$ be the highest?

A$$[Co(CN)_6]^{3-}$$
Correct Answer
B$$[Co(C_2O_4)_3]^{3-}$$
C$$[Co(H_2O)_6]^{3+}$$
D$$[Co(NH_3)_6]^{3+}$$

Solution

Other factors are same i.e. same central atom (Co) and same charge on the central atom (+3). The complex having strong field ligand has the highest magnitude of $$\Delta_0$$.
