MCQ
A substance which is not paramagnetic is
- A$Cr(ClO_4)_3$
- ✓$KMnO_4$
- C$TiCl_3$
- D$VOBr_2$
✓
Answer
Correct option: B.
$KMnO_4$
b
As we know, magnetic moment
As we know, magnetic moment
$\mu=\sqrt{ n ( n +2)} BM$
$KMnO _4$
$+7 \quad n =0 \quad$ diamagnetic
$\operatorname{Cr}\left( ClO _4\right)_3$
$+3 \quad n =3 \quad$ paramagnetic
$TiCl _3$
$+3 \quad n =1 \quad$ paramagnetic
$VOBr _2$
$+4 \quad n =1 \quad$ paramagnetic
