The species that undergoes diproportionation in an alkaline medium are:

A

`Cl_(4)`

B

`MnO_(4)^(2-)`

C

`NO_(2)`

D

`ClO_(4)^(-)`

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
`MnO_(4)^(2-), Cl_(2) and NO_(2)` undergo disproportional, oxidation and reduction simultaneously take place in the alkaline mediujm.
`Cl_(2)+2NaOH to NaCl +NaOCl+H_(2)O`
`2NO_(2)+2NaOH to NaNO_(2)+NaNO_(3)+H_(2)O`
`MnO_(4)^(2-)` is stable in strong alkali solution and disproportionate into `MnO_(4)^(-) and MnO_(2)` is less basic, Acidic and Neutral medium.
