Which of the following oxoacids of phosphorus has the highest oxidation state for phosphorus?
Phosphoric acid
Pyrophosphoric acid
Hypophosphorous acid
Perphosphoric acid
Correct Option D
Perphosphoric acid has the highest oxidation state for phosphorus (+5) because it contains five oxygen atoms bonded to the central phosphorus atom. Hence option D is the correct answer.
Option (A) is incorrect because perphosphoric acid has the highest oxidation state for phosphorus (+5) because it contains five oxygen atoms bonded to the central phosphorus atom. Hence option A is incorrect.
Option (B) is incorrect because perphosphoric acid has the highest oxidation state for phosphorus (+5) because it contains five oxygen atoms bonded to the central phosphorus atom. Hence option B is incorrect.
Option (C) is incorrect because perphosphoric acid has the highest oxidation state for phosphorus (+5) because it contains five oxygen atoms bonded to the central phosphorus atom. Hence option C is incorrect.
