Question

Which of the following equation is correct? Can be more than one.

Answer 1

There are actually no disproportionation reaction in the question. They are all incomplete and unbalanced.

Example of a disproportionate reaction:

`Cl_(2(g))+2OH_((aq))^-\rightarrow Cl_((aq))^-+ClO_((aq))^-+H_2O`

For this reaction the chlorine atom on the reactant side as an oxidation state of 0. It gets reduced to -1 in Cl- and oxidized to +1 in ClO3-
