The correct order of field strength of the following ligands is
- A \(\mathrm{N}^{3-}>\mathrm{C}_2 \mathrm{O}_4^{2-}>\mathrm{NH}_3>\mathrm{CO}\)
- B \(\mathrm{N}^{3-}>\mathrm{NH}_3>\mathrm{C}_2 \mathrm{O}_4^{2-}>\mathrm{CO}\)
- C \(\mathrm{CO}>\mathrm{NH}_3>\mathrm{C}_2 \mathrm{O}_4^{2-}>\mathrm{N}^{3-}\)
- D \(\mathrm{CO}>\mathrm{N}^{3-}>\mathrm{NH}_3>\mathrm{C}_2 \mathrm{O}_4^{2-}\)
Answer & Solution
Correct Answer
(C) \(\mathrm{CO}>\mathrm{NH}_3>\mathrm{C}_2 \mathrm{O}_4^{2-}>\mathrm{N}^{3-}\)
Step-by-step Solution
Detailed explanation
Based on spectrochemical series, ligands are arranged in increasing order of crystal field strength \[ \mathrm{CO}>\mathrm{NH}_3>\mathrm{C}_2 \mathrm{O}_4^{2-}>\mathrm{N}^{3-} \] Among the following ligands, \(\mathrm{CO}\) is the strongest ligand, while \(\mathrm{N}^{3-}\) is…
