Question

Thermal decomposition of a Mn compound (X) at 513 K results in compound Y, \ceMnO2\ce{MnO2} and a gaseous product. \ceMnO2\ce{MnO2} reacts with \ceNaCl\ce{NaCl} and concentrated \ceH2SO4\ce{H2SO4} to give a pungent gas Z. X, Y and Z, respectively, are: (1) \ceK3MnO4,K3MnO4\ce{K3MnO4, K3MnO4} and \ceCl2\ce{Cl2} (2) \ceK2MnO4,KMnO4\ce{K2MnO4, KMnO4} and \ceCl2\ce{Cl2} (3) \ceK2MnO4,KMnO4\ce{K2MnO4, KMnO4} and \ceSO2\ce{SO2} (4) \ceKMnO4,K2MnO4\ce{KMnO4, K2MnO4} and \ceCl2\ce{Cl2}

Options
  1. a

    \ceK3MnO4,K3MnO4\ce{K3MnO4, K3MnO4} and \ceCl2\ce{Cl2}

  2. b

    \ceK2MnO4,KMnO4\ce{K2MnO4, KMnO4} and \ceCl2\ce{Cl2}

  3. c

    \ceK2MnO4,KMnO4\ce{K2MnO4, KMnO4} and \ceSO2\ce{SO2}

  4. d

    \ceKMnO4,K2MnO4\ce{KMnO4, K2MnO4} and \ceCl2\ce{Cl2}

Correct Answerd

\ceKMnO4,K2MnO4\ce{KMnO4, K2MnO4} and \ceCl2\ce{Cl2}
