Phosphorus forms a number of oxoacids. Out of these oxoacids,phosphinic acid $(H_3PO_2)$ has strong reducing properties. Write its structure and also write a reaction showing its reducing behavior.
(N/A) The structure of phosphinic acid $(H_3PO_2)$ is as follows:
$P$ is bonded to one $O$ atom via a double bond,one $-OH$ group,and two $H$ atoms.
Structure:
$H-P(=O)(H)-OH$
Phosphinic acid acts as a good reducing agent because of the presence of two $P-H$ bonds.
Reaction showing its reducing behavior:
$4AgNO_3 + 2H_2O + H_3PO_2 \rightarrow 4Ag + 4HNO_3 + H_3PO_4$
