Phosphorus forms a number of oxoacids. Out of these oxoacids phosphinic acid has strong reducing property. Write its structure and also write a reaction showing its reducing behaviour.
Show answer
Structure of phosphinic acid (Hypophosphorous acid) is as follows : Reducing behaviour of phosphinic acid is observable in the reaction with silver nitrate given below : 4AgNO3 + 2H2O + H3PO2 → 4Ag + 4HNO3 + H3PO4 103 p-Block Elements IV. Matching Type
