Manganese $(VI)$ has the ability to disproportionate in an acidic solution. The difference in oxidation states of the two ions it forms in an acidic solution is $...... .$

The species which does not undergo disproportionation reaction is:

Observe the following reaction:
$Cl_{2(g)} + 2OH^{-}_{(aq)} \rightarrow ClO^{-}_{(aq)} + Cl^{-}_{(aq)} + H_2O_{(l)}$
Identify the correct statements about this reaction:
$I$. $Cl_{2(g)}$ is oxidized to $ClO^{-}_{(aq)}$
$II$. $Cl_{2(g)}$ is oxidized to $Cl^{-}_{(aq)}$
$III$. $Cl_{2(g)}$ is reduced to $ClO^{-}_{(aq)}$
$IV$. $Cl_{2(g)}$ is reduced to $Cl^{-}_{(aq)}$
The correct answer is:

Which of the following is only a redox reaction but not a disproportionation reaction?

In acidic solution, $MnO_4^{2-}$ converts into . . . . . . .

Among $P_4$,$S_8$ and $N_2$,the elements which undergo disproportionation when heated with $NaOH$ solution are:
