Question

Consider the following reaction MnO2 + KOH + O2 A + H2O. Product ‘A’ in neutral or acidic medium disproportionate to give products ‘B’ and ‘C’ along with water. The sum of spin-only magnetic moment values of B and C is __________ BM. (nearest integer) (Given atomic number of Mn is 25)

Prashant Kotian · Accepted Answer

Correct answer: .. MnO2 + KOH + O2  K2MnO4 + H2O (A) K2MnO4  Neutral/acidic solution KMnO4 + MnO2 Mn+4 :- [Ar]3d3 n = 3,  = 3(3 2)  = 3.87 B.M. Nearest integer is (4)
