Question

Number of P-O-P bonds in H₃PO₄, P₄O₁₀, (HPO₃)₃

Hint:

Count P–O–P bonds based on structural diagrams of the compounds

Answer 1

Bonds in Each Compound: 

• \( H_4P_2O_7 \) (Pyrophosphoric Acid): Contains one P–O–P bond as it has a linear structure connecting two phosphate groups.
• \( (HPO_3)_3 \) (Cyclotriphosphoric Acid): Contains three P–O–P bonds as it forms a cyclic structure with alternating P and O atoms.
• \( P_4O_{10} \) (Phosphorus Pentoxide): Contains six P–O–P bonds in its tetrahedral structure, where four phosphorus atoms are connected by oxygen bridges.

Summary:

• \( H_4P_2O_7 \): 1 P–O–P bond
• \( (HPO_3)_3 \): 3 P–O–P bonds
• \( P_4O_{10} \): 6 P–O–P bonds
