Question

An acidified manganate solution undergoes disproportionation reaction. The spin-only magnetic moment value of the product having manganese in higher oxidation state is ____ B.M. (Nearest integer)

Answer 1

The correct answer is: 00.00

$3MnO_4^{2−}+⟶{H^+}MnO_2+MnO_4^-+H_2O$
M+7= no. of unpaired electrons is '0'
Hence, magnetic moment = zero
