Question
The complex (A) is formed when FeSO4 reacts with excess of KCN. Complex (A) is oxidised into complex (B) by suitable oxidizing agent. From complex (B) three ligands are replaced by another three ligands (all are of same type and nonambidentate ligand) to form complex (C). From complex (B) when 4 ligands are replaced by another 4 ligands (of same type and nonambidentate ligand) it forms complex (D).
