प्रश्न
Give reasons H3PO3 undergoes disproportionation reaction but H3PO4 does not.
उत्तर
In H3PO3, P is present in +3 oxidation state while in H3PO4, P is present in +5 oxidation state. Since, in H3PO4, P is present in the maximum oxidation state, so it does not undergo disproportionation reaction. The reaction for disproportionation of H3PO3 is given as follows:
