MCQ
Among the following, the compound that is both paramagnetic and coloured is
- A${K_2}C{r_2}{O_7}$
- B${(N{H_4})_2}(TiC{l_6})$
- ✓$VOS{O_4}$
- D${K_3}\left[ {Cu(C{N_4})} \right]$
✓
Answer
Correct option: C.
$VOS{O_4}$
c
(c)${V^{ + 4}}\, \to \,\,3{d^1}4{s^0}$
(c)${V^{ + 4}}\, \to \,\,3{d^1}4{s^0}$
$1 $ unpaired electrons.
Hence, it is paramagnetic and coloured compound.
