Which does not undergo comproportionation reaction?

Options

A. `H_(2)S+SO_(2) to `
B. `I^(-)(aq.)+IO_(3)^(-)(aq.)+H^(+)(aq.)to`
C. `K_(2)MnO_(4)+H^(+)(aq.)to`
D. `MnO_(4)^(-)+Mn^(2+)(aq.)to`

Answer

C

Explanation

`H_(2)S uarr+SO_(2)uarr overset("Comprop.")to S darr+H_(2)O`
`I^(-)(aq.)+IO_(3)^(-)(aq.)+H^(+)(aq.)to overset("Comprop.")toI_(2)+H_(2)O`
`K_(2)MnO_(4)+H^(+)(aq.) overset("disprop.")toKMnO_(4)+MnO_(2)darr`
`MnO_(4)^(-)(aq.)+Mn^(2+)(aq.) overset("Comprop.")to MnO_(2)darr`
