2. Explain the following observations: (a) Co(III) forms strong bonds to O- and N-donor ligands, moderately strong bonds to P-donor ligand, and weak bonds to As-donor ligands. (b) EDTA4 forms more stable complexes with trivalent first-row transition metals (M3+) than it does with the corresponding divalent metal (M²+) of each (e.g. Cr²+ vs Cr3+). EDTA is a common ligand which bonds a metal center through four oxygen and two nitrogen atoms in an octahedral geometry (Figure 1). Figure 1. EDTA binds in an octahedral geometry
