MCQ
The most stable ion is
- A$[Fe(C_2O_4)_3]^{3-}$
- ✓$[Fe(CN)_6]^{3-}$
- C$[Fe(CN)_6]^{4-}$
- D$[Fe(H_2O)_6]^{3+}$
✓
Answer
Correct option: B.
$[Fe(CN)_6]^{3-}$
b
Among the given complexes the most stable is $\left[ Fe ( CN )_6\right]^{3-}$ because only this complex is forming a inner orbital complex because of the presence of a strong field ligand and its hybridization is $d^2 s p^3$ while rest of the complexes forms a outer orbital complex which are less stable in comparison.
