प्रश्न
Give reasons for the following : H3PO2 is a stronger reducing agent than H3PO3.
Advertisements
उत्तर १
Greater the number of element−hydrogen (E−H) bonds present in a compound, greater is the reducing nature of the compound. H3PO2has two P−H bonds while H3PO3 has one P−H bond. Thus, H3PO2 is a stronger reducing agent than H3PO3.
उत्तर २
In case of H3PO3, there is only one P-H bond while in case of H3PO2, there are two P-H bonds. Hence H3PO2 is better reducing agent than H3PO3.
