Question

Consider the hydrated ions of $\ce{Ti^{2+}}$ , $\ce{V^{2+}}$ , $\ce{Ti^{3+}}$ and $\ce{Sc^{3+}}$ . The correct order of their spin-only magnetic moments is:

Options

a
$\ce{Sc^{3+}} < \ce{Ti^{3+}} < \ce{V^{2+}} < \ce{Ti^{2+}}$
b
$\ce{Ti^{3+}} < \ce{Ti^{2+}} < \ce{Sc^{3+}} < \ce{V^2{+}}$
c
$\ce{Sc^{3+}} < \ce{Ti^{3+}} < \ce{Ti^{2+}} < \ce{V^{2+}}$
✓
d
$\ce{V^{2+}} < \ce{Ti^{2+}} < \ce{Ti^{3+}} < \ce{Sc^{3+}}$

Correct Answerc

$\ce{Sc^{3+}} < \ce{Ti^{3+}} < \ce{Ti^{2+}} < \ce{V^{2+}}$
