- A \(\left[\mathrm{Co}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right]^{3+}\)
- B \(\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_6\right]^{3+}\)
- C \(\left[\mathrm{Co}\left(\mathrm{C}_2 \mathrm{O}_4\right)_3\right]^3\)
- D \(\left[\mathrm{CoF}_6\right]^3\)
Answer & Solution
Correct Answer
(B) \(\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_6\right]^{3+}\)
Step-by-step Solution
Detailed explanation
The crystal field splitting, i.e. \(\Delta_0\), depends upon the field produced by the ligand and charge on the metal ion. So, ligands can be arranged in a series in the order of increasing field strength. This series is known as spectrochemical series. e.g.,…
