What products are expected from disproportionation reaction of orthophosphorus acid?

1.\,\,{{H}_{3}}P{{O}_{3}}+P{{H}_{3}}

2.\,\,{{H}_{3}}P{{O}_{4}}+P{{H}_{3}}

3.\,\,P{{H}_{3}}+{{P}_{2}}{{O}_{5}}

4.\,\,{{H}_{3}}P{{O}_{3}}+{{P}_{2}}{{O}_{5}}

Solution:  2.\,\,{{H}_{3}}P{{O}_{4}}+P{{H}_{3}}

Disproportionation is a sort of redox reaction in which an element undergoes both oxidation and reduction to produce two distinct products. Similarly, disproportionation on heating produces two products in the case of H3PO3. When H3PO3 is heated, a disproportionation reaction occurs, resulting in ortho phosphoric acid and phosphine.
