Question

Which among the following oxoacids of phosphorus will have P-O-P bonds?

I. H₄P₂O₅

II. H₄P₂O₆

III. H₄P₂O₇

IV. (HPO₃)₃

 

• A. \( III, IV \)
• B. \(I, II\)
• C. \(I, III\)
• D. \(II, IV\)

Hint:

Phosphorus oxoacids such as \(\text{H}_4\text{P}_2\text{O}_7\) and (\(\text{HPO}_3\))\(_3\) exhibit P-O-P bonding due to the structure of their molecular formula.

Answer 1

The Correct Option is A

The phosphorus oxoacids \(\text{H}_4\text{P}_2\text{O}_7\) and (\(\text{HPO}_3\))\(_3\) contain P-O-P bonds in their molecular structure. These acids have phosphoric acid groups that form bonds between phosphorus atoms, creating a P-O-P linkage. The oxoacids \(\text{H}_4\text{P}_2\text{O}_5\) and \(\text{H}_4\text{P}_2\text{O}_6\) do not form P-O-P bonds in their molecular structures.
