MCQ
The $[Fe(CN)_6 ]^{3-}$ complex ion
- Aexhibits planar geometry
- Bis diamagnetic
- ✓should be very stable
- Dhas $2$ unpaired electrons
✓
Answer
Correct option: C.
should be very stable
c
Both the high charge density of $Fe^{3+}$ in $[Fe(CN)_6]^{3-}$ and strong basic (Lewis) character of the ligand $CN^-$ attribute to the stability of the complex.
