A) \[MnO_{4}^{2-},M{{n}^{3+}}\]and\[M{{n}^{2+}}\]
B) \[Mn{{O}_{2}},Mn{{O}_{2}}\]and\[M{{n}^{2+}}\]
C) \[Mn{{O}_{2}},Mn{{O}_{2}}^{+}\]and\[M{{n}^{3+}}\]
D) \[MnO,Mn{{O}_{2}}\]and\[M{{n}^{2+}}\]
Correct Answer: B
Solution :
In neutral and alkaline medium \[MnO_{4}^{-}+2{{H}_{2}}O+3{{e}^{-}}\xrightarrow[{}]{{}}Mn{{O}_{2}}+4O{{H}^{-}}\] In acidic medium: \[MnO_{4}^{-}+8{{H}^{+}}+5{{e}^{-}}\xrightarrow[{}]{{}}M{{n}^{2+}}+4{{H}_{2}}O\]
