A) \[{{C}_{6}}{{H}_{6}}+{{H}_{2}}{{O}_{2}}\xrightarrow[{}]{{}}{{C}_{6}}{{H}_{5}}OH+{{H}_{2}}O\]
B) \[2{{I}^{-}}+2{{H}^{+}}+{{H}_{2}}{{O}_{2}}\xrightarrow{{}}{{I}_{2}}+{{H}_{2}}O\]
C) \[2MnO_{4}^{-}+6{{H}^{+}}+5{{H}_{2}}{{O}_{2}}\xrightarrow{{}}\]\[2M{{n}^{2+}}+5{{O}_{2}}+8{{H}_{2}}O\]
D) \[PbS+4{{H}_{2}}{{O}_{2}}\xrightarrow[{}]{{}}PbS{{O}_{4}}+4{{H}_{2}}O\]
Correct Answer: C
Solution :
\[2MnO_{4}^{-}+6{{H}^{+}}+5{{H}_{2}}{{O}_{2}}\xrightarrow[{}]{{}}2M{{n}^{2+}}+8{{H}_{2}}O+5{{O}_{2}}\] or, \[2Kmn{{O}_{4}}+3{{H}_{2}}S{{O}_{4}}+5{{H}_{2}}{{O}_{2}}\xrightarrow[{}]{{}}\] \[{{K}_{2}}S{{O}_{4}}+2MnS{{O}_{4}}+8{{H}_{2}}O+5{{H}_{2}}O\]
