Phosphorus forms a number of oxoacids. Out of these oxoacidsphosphinicacid has strong reducing property. Write its structure and also write a reaction showing its reducing behaviour.

REACTIONS SHOWING REDUCING BEHAVIOR:

4AgNO3 + H3PO2 + 2H2O 4Ag + H3PO4 + 4HNO3


2HgCl2 + H3PO2 + 2H2O 2Hg + H3PO4 + 4HCl




It shows reducing behavior due to possession of P-H bond
