Question

Amongst [fe(c2o4)3]3- and [fe(nh3)6}3+which is more stable and why

Answer 1

Hey Dear,

◆ Answer -

[Fe(C2O4)3]3-

◆ Explaination -

• In both complexes, central ion is Fe3+.
• In [Fe(NH3)6]3+, NH3 is a unidentate neutral ligand. It doesn't form chelation complex.
• In [Fe(C2O4)3]3-, (C204)2- is a bidentate negative ligand.
• Due to chelation by (C204)2-, [Fe(C2O4)3]3- is more stable than [Fe(NH3)6]3+.

Thanks...
