Why is H3PO2 a stronger reducing agent than H3PO3.
1) Reducing agents are those molecules which can donate electrons. 2) The donating elctrons are hydrogen atoms which are bonded to phosphorus atom. 3) In case of H3PO2 there are two hydrogen bonded toP atom but in case of H3PO3 there are only one hydrogen bonded to Patom has more donating electrons than . 4)Therefore ,H3PO2 is stronger reducing
