Question

Write the names and structures of oxoacids of phosphorus in which phosphorus exists in +7 oxidation state.

Answer 1

Phosphorus does not form stable oxoacids in the +7 oxidation state. The highest oxidation state in common oxoacids of phosphorus is +5. No well-defined oxoacid with phosphorus in the +7 oxidation state is known. Therefore, phosphorus +7 oxoacids do not exist in stable form.
