Coordination chem

a kyun nahin??

`bidentate ligand hai na is liye

C₂O₄???`

C₂O₄^2- is bidentate,
en (ethylene diamine) is also bidentate
so coordination number is 6
en is neutral and C2O4 is 2- hence charge on centre shud be 3+
Hence B)
cheers!!

C₂O₄ ²- oxalato is bidentate,
en =ethylene diamine is bidentate and neutral ligand
so coordination number is 6
en is neutral and C₂O₄ ²- has 2- charge hence charge on E should be 3+
so its b
