$Cr^{2+} < Mn^{2+} < Fe^{2+}$ - Paramagnetic behaviour

Vedclass · Answer

(C) The property stated against option $(C)$ is incorrect.The electronic configurations of the given ions are:$Cr^{2+} = [Ar] 3d^4$ ($4$ unpaired electrons)$Mn^{2+} = [Ar] 3d^5$ ($5$ unpaired electrons)$Fe^{2+} = [Ar] 3d^6$ ($4$ unpaired electrons)Paramagnetic behaviour is directly proportional to the number of unpaired electrons.Since $Mn^{2+}$ has $5$ unpaired electrons,it shows the maximum paramagnetic behaviour among the three.Therefore,the correct order of paramagnetic behaviour is $Cr^{2+} = Fe^{2+} < Mn^{2+}$.
