The spin-only magnetic moment value of the most basic oxide of vanadium among V2O3, V2O4 and V2O5 is _____________ B.M. (Nearest integer)
Answer (integer)
3
Solution
The most basic oxide among $\mathrm{V}_{2} \mathrm{O}_{3}, \mathrm{~V}_{2} \mathrm{O}_{4}$ and $\mathrm{V}_{2} \mathrm{O}_{5}$ is $\mathrm{V}_{2} \mathrm{O}_{3}$
<br/><br/>
$\mathrm{V}_{2} \mathrm{O}_{3}=\mathrm{V}^{+3}\left(\mathrm{~d}^{2}\right)$
<br/><br/>
Magnetic moment $=\sqrt{2(2+2)}=\sqrt{8}$
<br/><br/>
$=2.83 \approx 3$
