Account for the following :
H3PO2 is a stronger reducing agent than H3PO3.
उत्तर
Greater the number of element-hydrogen (E−H) bonds present in a compound, greater is the reducing power of the compound. H3PO2 is a stronger reducing agent as it contains 2 P−H bonds, while H3PO3 has only one P−H bond.
