A) \[MnO_{4}^{2-}\]
B) \[MnO_{4}^{3-}\]
C) \[C{{u}^{+}}\]
D) \[C{{r}^{2+}}\]
Correct Answer: A
Solution :
(1)\[MnO_{4}^{2-}\] disproportionates in neutral or acidic solution. \[3MnO_{4}^{2-}+4{{H}^{+}}\xrightarrow[{}]{{}}2MnO_{4}^{2-}+Mn{{O}_{2}}+2{{H}_{2}}O\](3) Many Cu+ compounds are unstable in aqueous solution and undergo disproportionation as follows\[2C{{u}^{+}}\xrightarrow[{}]{{}}C{{u}^{2+}}+Cu\]
