The complex that has the highest crystal splitting energy $$(\Delta)$$, is:

A$$K_3[Co(CN)_6]$$
Correct Answer
B$$[Co(NH_3)_2(H_2O)]Cl_3$$
C$$[Co(NH_3)_3(H_2O)]Cl_3$$
D$$[Co(NH_3)_5Cl]Cl_2$$

Solution

Crystal Field Theory -

According to this theory, metal and ligand are considered as point charges. This theory deals with electrostatic force of attraction means the talks about the ionic character of M-L bond.


As complex $$K_3[Co(CN)_6]$$ have $$CN^-$$ ligand which is strongfield ligand amongst the given ligand in other complexes.
