Step-by-step Solution

Detailed explanation

Increasing order of ligand field strength is:
\(\mathrm{I}^{-} \lt \mathrm{Br}^{-} \lt \mathrm{Cl}^{-} \lt \mathrm{S}^{2-} \lt \mathrm{F}^{-} \lt \mathrm{OH}^{-} \lt \mathrm{C}_2 \mathrm{O}_4^{2-}\)
\(\lt \mathrm{H}_2 \mathrm{O} \lt \mathrm{NCS}^{-} \lt \mathrm{EDTA} \lt \mathrm{NH}_3 \lt \mathrm{en}\) \(\lt \mathrm{CN} \lt \mathrm{CO}\)
