As we learned

 

Hypophosphoric Acid -

H4P2O6 (+4), tetrabasic

- wherein

Hyphophosphoric Acid

 

 

Orthophosphoric Acid -

H3PO4 (+5), tribasic

- wherein

Orthophosphoric acid

 

 Pyrophosphorous acid has the formula H4P2O5

  Oxidation state of P = +3

Orthophosphorous acid has the formula H3PO3 

  Oxidation state of P = +3

 

 


Option 1)

Orthophosphorous and pyrophosphorous acids

 

Option 2)

Pyrophosphorous and hypophosphoric acid

Option 3)

Orthophosphorous and hypophosphoric acids

 

Option 4)

 Pyrophosphorous and pyrophosphoric acids
