Which of the following statements is incorrectA. In `K_(3)[Fe(CN)_(6)]

1.	Which of the following statements is incorrectA. In `K_(3)[Fe(CN)_(6)]`, the ligand has satisfied only the secondary valencies of ferric ionB. In `K_(3)[Fe(CN)_(6)]`, the ligand has satisfied both primary and secondary valencies of ferric ionC. In `K_(4)[Fe(CN)_(6)]`, the ligand has satisfied both primary and secondary valencies of ferrous ionD. In `[Cu(NH_(3))_(4)]SO_(4)` , the ligand has satisfied only the secondary valencies of copper
Answer» Correct Answer - A::D In `K_(3)[Fe(CN)_(6)]` the ligand are negative which is present in coordination spheres shows a dual behaviour. It may satisfy both primary & secondary valencies while neutral ligand satisfies only secondary valencies.
