Answer 2

The oxide which cannot undergo a disproportionation reaction is N2O3.

• N2O3 cannot undergo a disproportionation reaction.
• N2O3 is in its highest oxidation state.
• The disproportionation reaction is that reaction in which one element is oxidized and reduced simultaneously.
• As N2O3 is in the highest oxidation state, it cannot further undergo oxidation or reduction, So it does not show a disproportionation reaction.

Hence, N2O3 cannot undergo a disproportionation reaction.
