$V^{2+} < Cr^{2+} < Mn^{2+} < Fe^{2+}$ (Paramagnetic property)

Vedclass · Answer

(A) Let us analyze each option:$A$: Paramagnetic property depends on the number of unpaired electrons. $V^{2+} (d^3, 3), Cr^{2+} (d^4, 4), Mn^{2+} (d^5, 5), Fe^{2+} (d^6, 4)$. The sequence $V^{2+} $B$: Ionic size generally decreases across the period due to increasing effective nuclear charge. The sequence $Ni^{2+} $C$: Stability in aqueous solution depends on electrode potentials. $Sc^{3+}$ is the most stable due to noble gas configuration. The sequence is correct.$D$: The number of oxidation states increases as the number of unpaired electrons increases. The sequence $Sc Therefore,option $A$ is the incorrect sequence.
