Pyrolusite ore on oxidation with `KCIO_(3)//KNO_(3)` in basic medium produces dark green coloured compound `(A)`, which on electrolysis produces a purple coloured compound `(B)`. The purple coloured rhombic prisms. It shows different reactions in different mediums. Excess of compounds (B) on heating with conc. `H_(2)SO_(4)` gives an explosive oil (C ), which on heating decomposes to gives another compound (D ) along with oxygen. On passing `CO_(2)` in the solution of (A), a purple coloured solution along with brown ppt is observed.A. This is a disproportionation reaction where oxidation number changes from +6 to +7, +4.B. This is a comproportionation reaction where oxidation number changes from +3 to +2C. Both A and BD. none
