Which among the following oxoacids of phosphorus shows a tendency of d – InterviewSolution

1.	Which among the following oxoacids of phosphorus shows a tendency of disproportaonation ?A. Phosphinic acid `(H_(3)PO_(2))`B. Orthophosphoric acid `(H_(3)PO_(4))`C. Phosphonic acid `(H_(3)PO_(3))`D. Pyrophosphoric acid `(H_(4)P_(2)O_(7))`
Answer» Correct Answer - C Phosphonic acid `(H_(3)PO_(3))`, oxoacid of Phosphorus shows a tendency of disproportionation. On heating `H_(3)PO_(3)` disproportionates to give orthophosphoric acid and phoosphene gas. `4H_(3)PO_(3)overset(Delta)to3H_(3)PO_(4)+PH_(3)`
