Phosphonic acid

B

Phosphinic acid

C

Orthophosphoric acid

D

Pyrophosphoric acid

Text Solution

Verified by Experts

The correct Answer is:
B
Phosphorus forms various oxyacids. They are `H_(3)PO_(2), H_(3)PO_(3), H_(3)PO_(4), H_(4)P_(2)O_(7) " and "(HPO_(2))_(n)` etc. Phosphinic acid `(H_(3)PO_(2))`. It is set up by the oxidation of phosphine by iodine within the sight of figured amount of water. It is a monobasic acid.
`PH_(3)+2I_(2)+2H_(2)O rarr H_(3)PO_(2)+4HI`
