1.	Phosphorus forms a number of oxoacids. Out of these oxoacids, phosphinic acid has strong reudcing property. Write its structure and also write a reaction showing its redcuing behaviour.
Answer» Solution :The STRUCTURE of phosphinic acid (hypophosphorus acid) is GIVEN on the R.H.S. Since it contains two P-H bonds, it acts as a strong reducing agent. For example, it reduces `AgNO_(3)` to metallic SILVER. `4 AgNO_(3) + H_(3)PO_(2) + 2H_(2)O rarr 4Ag darr H_(3)PO_(4) + 4 HNO_(3)`
