The order of the oxidation state of the phosphorus atom in H3PO2,H3PO4,H3PO3{H}_{3}P{O}_{2}, {H}_{3}P{O}_{4}, {H}_{3}P{O}_{3} and H4P2O6{H}_{4}{P}_{2}{O}_{6} isThe order of the oxidation state of the phosphorus atom in H _ 3 P O _ 2 , H _ 3 P O _ 4 , H _ 3 P O _ 3 and H _ 4 P _The order of the oxidation state of the phosphorus atom in H _ 3 P O _ 2 , H _ 3 P O _ 4 , H _ 3 P O _ 3 and H _ 4 P _The order of the oxidation state of the phosphorus atom in H _ 3 P O _ 2 , H _ 3 P O _ 4 , H _ 3 P O _ 3 and H _ 4 P _The order of the oxidation state of the phosphorus atom in H _ 3 P O _ 2 , H _ 3 P O _ 4 , H _ 3 P O _ 3 and H _ 4 P _

Options

  1. AH3PO4>H4P2O6>H3PO3>H3PO2{H}_{3}P{O}_{4} > {H}_{4}{P}_{2}{O}_{6} > {H}_{3}P{O}_{3} > {H}_{3}P{O}_{2}
  2. BH3PO3>H3PO2>H3PO4>H4P2O6{H}_{3}P{O}_{3} > {H}_{3}P{O}_{2} > {H}_{3}P{O}_{4} > {H}_{4}{P}_{2}{O}_{6}
  3. CH3PO2>H3PO3>H4P2O6>H3PO4{H}_{3}P{O}_{2} > {H}_{3}P{O}_{3} > {H}_{4}{P}_{2}{O}_{6} > {H}_{3}P{O}_{4}
  4. DH3PO4>H3PO2>H3PO3>H4P2O6{H}_{3}P{O}_{4} > {H}_{3}P{O}_{2} > {H}_{3}P{O}_{3} > {H}_{4}{P}_{2}{O}_{6}

Correct answer

A. H3PO4>H4P2O6>H3PO3>H3PO2{H}_{3}P{O}_{4} > {H}_{4}{P}_{2}{O}_{6} > {H}_{3}P{O}_{3} > {H}_{3}P{O}_{2}

Step-by-step solution

The order of the oxidation state of the phosphorus atom in H _ 3 P O _ 2 , H _ 3 P O _ 4 , H _ 3 P O _ 3 and H _ 4 P _

The order of the oxidation state of the phosphorus atom in H _ 3 P O _ 2 , H _ 3 P O _ 4 , H _ 3 P O _ 3 and H _ 4 P _

The order of the oxidation state of the phosphorus atom in H _ 3 P O _ 2 , H _ 3 P O _ 4 , H _ 3 P O _ 3 and H _ 4 P _

The order of the oxidation state of the phosphorus atom in H _ 3 P O _ 2 , H _ 3 P O _ 4 , H _ 3 P O _ 3 and H _ 4 P _

Hence answer is H3PO4>H4P2O6>H3PO3>H3PO2{H}_{3}P{O}_{4} > {H}_{4}{P}_{2}{O}_{6} > {H}_{3}P{O}_{3} > {H}_{3}P{O}_{2}
