Arrange the following in the increasing order of property mentioned :
H3PO3, H3PO4, H3PO2 (Reducing character)
(a) Reducing character: H3PO4 < H3PO3 < H3PO2
This trend can be explained on the basis of structures of oxyacids of phosphorus.
The higher the number of P−H bond, the higher the reducing power of the oxyacid of phosphorus. There are two P−H bonds in H3PO2, one P−H bond in H3PO3 and no P−H bond in H3PO4. So, this explains the reducing trend of the given oxyacids of phosphorus.
