Pyrolusite ore on oxidation with `KClO_(3)`/`KNO_(3)` in basic medium produces dark green coloured compound "(A)," which on electrolysis produces a purple coloured compound (B).The purple coloured compound can be crystallised to deep purple rhombic prisms.It shows different reactions in different mediums.Excess of compound (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.Identify (D)

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.
