Which one of the following is not correct?
- A Pyrophosphoric acid is a tetrabasic acid
- B Pyrophosphoric acid contains \(\mathrm{P}-\mathrm{O}-\mathrm{P}\) linkage
- C Pyrophosphoric acid contains two \(\mathrm{P}-\mathrm{H}\) bonds
- D Orthophosphoric acid can be prepared by dissolving \(\mathrm{P}_4 \mathrm{O}_{10}\) in water
Answer & Solution
Correct Answer
(C) Pyrophosphoric acid contains two \(\mathrm{P}-\mathrm{H}\) bonds
Step-by-step Solution
Detailed explanation
In pyrophosphoric acid \(\left(\mathrm{H}_4 \mathrm{P}_2 \mathrm{O}_7\right)\), the phosphorus is bonded in tetrahedral manner with four \(s p^3\) bonds. It has +5 oxidation state and it has four \(\mathrm{P}-\mathrm{OH}\) bonds, two \(\mathrm{P}=\mathrm{O}\) bonds and one…
