JEE MAIN - Chemistry (2022 - 26th June Morning Shift - No. 16)
The spin-only magnetic moment value of the most basic oxide of vanadium among V2O3, V2O4 and V2O5 is _____________ B.M. (Nearest integer)
Answer
3
Explanation
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 $\mathrm{V}_{2} \mathrm{O}_{3}$
$$ \mathrm{V}_{2} \mathrm{O}_{3}=\mathrm{V}^{+3}\left(\mathrm{~d}^{2}\right) $$
Magnetic moment $=\sqrt{2(2+2)}=\sqrt{8}$
$$ =2.83 \approx 3 $$
$$ \mathrm{V}_{2} \mathrm{O}_{3}=\mathrm{V}^{+3}\left(\mathrm{~d}^{2}\right) $$
Magnetic moment $=\sqrt{2(2+2)}=\sqrt{8}$
$$ =2.83 \approx 3 $$
