JEE Main 2024 — 6 April, Shift 2 — Question 86

Among VO2+,MnO4−\mathrm{VO}_{2}^{+}, \mathrm{MnO}_{4}^{-}and Cr2O72−\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 V=23,Mn=25,Cr=24\mathrm{V}=23, \mathrm{Mn}=25, \mathrm{Cr}=24 )

Answer: 0

Numerical answer — enter this value.

Step-by-step solution

For 3d transition series;

Oxidising power : V+5<Cr+6<Mn+7\mathrm{V}^{+5}<\mathrm{Cr}^{+6}<\mathrm{Mn}^{+7} V+5:[Ar]4 s03 d0\mathrm{V}^{+5}:[\mathrm{Ar}] 4 \mathrm{~s}^{0} 3 \mathrm{~d}^{0}

Number of unpaired electron =0=0
