Vedclass · Answer

(B) The oxidizing ability of these oxoanions depends on the oxidation state and the stability of the lower oxidation states of the central metal atom. The order of oxidizing power is $VO_2^{+} Thus,$VO_2^{+}$ has the least oxidizing ability.In $VO_2^{+}$,the oxidation state of $V$ is $+5$.The electronic configuration of $V$ $(Z=23)$ is $[Ar] 3d^3 4s^2$.For $V^{+5}$,the configuration is $[Ar] 3d^0 4s^0$.Since there are no unpaired electrons $(n=0)$,the spin-only magnetic moment $\mu = \sqrt{n(n+2)} = \sqrt{0(0+2)} = 0 \ BM$.

Among $VO_2^{+}$,$MnO_4^{-}$ and $Cr_2O_7^{2-}$,the spin-only magnetic moment value of the species with least oxidising ability is $BM$ (Nearest integer). (Given atomic number $V=23$,$Mn=25$,$Cr=24$)
