Thermal decomposition of a Mn compound (X) at 513 K results in compound Y, MnO2 and gaseous product. MnO2 reacts with NaCl and concentrated H2O4 to give a pungent gas Z. X, Y and Z, respectively, are :

Multiple Choice Options

  • A KMnO4, K2MnO4 and Cl2
  • B K2MnO4, KMnO4 and SO2
  • C K3MnO4, K2MnO4 and Cl2
  • D K2MnO4, KMnO4 and Cl2

Step-by-Step Verified Solution

KMnO4 ⟶513K K2MnO4 + MnO2 + O2
(X) (Y)
MnO2 + NaCl + conc H2SO4 →\to MnSO4 + NaHSO4 + H2O + Cl2
(Z)
