$Mn^{2+} > Mn^{3+}$

Vedclass · Answer

(B) The stability of oxidation states in $d$-block elements is often determined by the electronic configuration.$Mn^{2+}$ has a $3d^5$ configuration,which is a half-filled stable configuration.$Mn^{3+}$ has a $3d^4$ configuration,which is less stable than the half-filled $3d^5$ state.Therefore,$Mn^{2+} > Mn^{3+}$ is the correct representation of stability.
