MCQ
The complex that has highest crystal field splitting energy $(\Delta )$ is
- A$[Co(NH_3)_5(H_2O)]Cl_3$
- B$K_2[CoCl_4]$
- C$[Co(NH_3)_5Cl]Cl_2$
- ✓$K_3[Co(CN)_6]$
✓
Answer
Correct option: D.
$K_3[Co(CN)_6]$
d
As $CN^-$ is a strong field ligand. $K_3[Co(CN)_6]$ will have maximum $‘\Delta ’.$
As $CN^-$ is a strong field ligand. $K_3[Co(CN)_6]$ will have maximum $‘\Delta ’.$
