D and F Block Elements question

2022 · 28 Jul · Shift 1 · Q20

JEE MainChemistryD and F Block ElementsNumerical+4 / −1
The disproportionation of MnO42−\mathrm{MnO}_{4}^{2-}MnO42−​ in acidic medium resulted in the formation of two manganese compounds A\mathrm{A}A and B\mathrm{B}B. If the oxidation state of Mn\mathrm{Mn}Mn in B\mathrm{B}B is smaller than that of A, then the spin-only magnetic moment (μ)(\mu)(μ) value of B in BM is ‾\underline{\hspace{2cm}}​. (Nearest integer)
