Answer 1

Answer:

Explanation:

I think you have misspelled H3PO3 as HPO3 .

Yeah for the explanation ,

• first find out the oxidation states of Phosphorus in all the 4 compounds
• in H3PO3 , Phosphorus is having +3
• in H3PO2 , Phosphorus is having +1

• in H4P2O7 and H3PO4 Phosphorus is having +5 , which is the maximum it can exhibit and it cant be further oxidized .
