QJEEM22Ch6284: JEE Main 2022 Chemistry - Class 12 JEEM22Ch6284 Solution: The spin-only magnetic moment value of the most basic oxide of…

The spin-only magnetic moment value of the most basic oxide of vanadium among V2O3, V2O4 and V2O5 is _____________ B.M. (Nearest integer)

Step-by-Step Verified Solution

The most basic oxide among V2O3, V2O4\mathrm{V}_{2} \mathrm{O}_{3}, \mathrm{~V}_{2} \mathrm{O}_{4} and V2O5\mathrm{V}_{2} \mathrm{O}_{5} is V2O3\mathrm{V}_{2} \mathrm{O}_{3}

V2O3=V+3( d2)\mathrm{V}_{2} \mathrm{O}_{3}=\mathrm{V}^{+3}\left(\mathrm{~d}^{2}\right)

Magnetic moment =2(2+2)=8=\sqrt{2(2+2)}=\sqrt{8}

=2.83≈3=2.83 \approx 3
