Consider the following list of ligands: Cl ⁻ , OH ⁻ , C ₂ O ₄²⁻ , NCS ⁻ , edta ⁴⁻ , NH ₃ , en , CN ⁻ How many of the given ligands have a higher field strength than H ₂ O according to the spectrochemical series?

Step-by-step solution

According to the spectrochemical series, the arrangement of ligands in increasing order of their field strength is: I ⁻ From the given list, the ligands with a lower field strength than H ₂ O are Cl ⁻ , OH ⁻ , and C ₂ O ₄²⁻ . The ligands with a higher field strength than H ₂ O are NCS ⁻ , edta ⁴⁻ , NH ₃ , en , and CN ⁻ . Thus, there are 5 ligands stronger than H ₂ O . Answer: 5
