Vedclass · Answer

For $3$d transition series;

Oxidising power : $\mathrm{V}^{+5}<\mathrm{Cr}^{+6}<\mathrm{Mn}^{+7}$

$\mathrm{V}^{-5}:[\mathrm{Ar}] 4 \mathrm{~s}^0 3 \mathrm{~d}^0$

Number of unpaired electron $=0$

$u=0$

Among $\mathrm{VO}_2^{+}, \mathrm{MnO}_4^{-}$and $\mathrm{Cr}_2 \mathrm{O}_7^{2-}$, the spin-only magnetic moment value of the species with least oxidising ability is...................$BM$ (Nearest integer).

(Given atomic member $\mathrm{V}=23, \mathrm{Mn}=25, \mathrm{Cr}=24$ )
