MCQ
The stability of ferric ion is due to:
- AHalf field $f-$orbital
- ✓Half field $d-$orbital
- CComplete field $f-$orbital
- DComplete field $d-$orbital
✓
Answer
Correct option: B.
Half field $d-$orbital
$\mathrm{Fe}^{3+}=\ce{1 s^2 2 s^2 2 p^6 3 s^2 3 p^6 3 d^5d}$ orbital is half filled.So ferric ion is stable.
