Consider the hydrated ions of $Ti^{2+}, V^{2+}, Ti^{3+}$ and $Sc^{3+}$. The correct order of their spin-only magnetic moments is
$Ti^{3+} < T^{2+} < Sc^{3+} < V^{2+}$
$Sc^{3+} < Ti^{3+} < Ti^2 < V^{2+}$
$V^{2+} < Ti^{2+} < Ti^{3+} < Sc^{3+}$
$Sc^{3+} < Ti^{3+} < V^{2+} < Ti^{2+}$
Magnetic moment $2.84\, B.M.$ is given by (At. nos. $Ni = 28, Ti = 22, $$Cr = 24, Co = 27$)
