MCQ
Which of the following complex will show maximum paramagnetism ?
- A$3d^4$
- ✓$3d^5$
- C$3d^6$
- D$3d^7$
✓
Answer
Correct option: B.
$3d^5$
b
Among high spin complexes, $3 d ^5$ will show maximum paramagnetism as it has maximum number of unpaired electrons.High spin $3 d^4, 3 d^5, 3 d^6$ and $3 d^7$ have $4,5,4$ and 3 unpaired electrons respectively.
