Q. Among $\left[Ni\left(CO\right)_{4}\right]\left[NiCl_{4}\right]^{2-}\left[Co\left(NH_{3}\right)_{4}Cl_{2}\right]Cl, Na_{3} \left[CoF_{6}\right], Na_{2}O_{2}$ and $CsO_{2}$ find the total number of paramagnetic compounds.
Coordination Compounds
Solution:
Compound/Ion
Magnetic nature of compound
$\left[Ni\left(CO\right)_{4}\right]$
Diamagnetic
$\left[NiCl_{2}\right]^{2-}$
Paramagnetic
$\left[Co\left(NH_{3}\right)_{4} Cl_{2}\right]Cl$
Diamagnetic
$Na_{3}\left[CoF_{6}\right]$
Paramagnetic
$Na_{2}O_{2}$
Diamagnetic
$CsO_{2}$
Paramagnetic
So total number of paramagnetic compounds is 3.
