Coordination Compounds Question 18
Question 18 - 2024 (31 Jan Shift 2)
Select the option with correct property -
(1) $\left[Ni(CO) _4\right]$ and $\left[NiCl _4\right]^{2-}$ both diamagnetic
(2) $\left[Ni(CO) _4\right]$ and $\left[NiCl _4\right]^{2-}$ both paramagnetic
(3) $\left[NiCl _4\right]^{2-}$ diamagnetic, $\left[Ni(CO) _4\right]$ paramagnetic
(4) $\left[Ni(CO) _4\right]$ diamagnetic, $\left[NiCl _4\right]^{2-}$ paramagnetic
Show Answer
Answer (4)
Solution
$\left[Ni(CO) _4\right] \rightarrow$ diamagnetic, $sp^{3}$ hybridisation, number of unpaired electrons $=0$
$\left[NiCl _4\right]^{2-}, \rightarrow$ paramagnetic, $sp^{3}$ hybridisation, number of unpaired electrons $=2$
