Question

Among the following, the ion with highest magnetic moment is .

• A. $T{i}^{2+}$
• B. $C{r}^{+}$
• C. $C{o}^{2+}$
• D. $N{i}^{2+}$

Answer 1

The correct option is B $C{r}^{+}$

$T{i}^{2+}$ has 2 unpaired electrons.
Magnetic moment = 2.82 BM.
$C{r}^{+}$ has 5 unpaired electrons.
Magnetic moment = 5.91 BM.
$C{o}^{2+}$ has 3 unpaired electrons.
Magnetic moment = 3.87 BM.
$N{i}^{2+}$ has 2 unpaired electrons.
Magnetic moment = 2.82 BM.
