From the following list, identify which compounds act as electron donors, electron acceptors, or both (hint: compute the oxidation states of the elements and compare to other compunds containing the same elements): O2, CO2, NH4+, SO42-, NO2-, NO3-, HS-, CH4, and Fe3+

00:01 Hello students welcome here in this question there is some compounds are given so if you see here o2 and c -o -2 is given and nh4 plus is given and so4 minus 2 is given and no2 minus and no3 minus is given and h3 minus is given and hs minus is given and hs minus and ch4 minus ch4 is given and here it is f .a.

00:35 Plus three is given.

00:37 So they are asking which is acting as electron acceptor and which is acting as electron donor and which is acting as both.

00:47 Okay.

00:48 So here the oxidation state plays an important rule.

00:52 So oxidation state is maximum.

00:55 Maximum oxidation state is present.

00:58 Then it is acting as acceptor.

01:00 Electron acceptor and if it is minimum then it is acting as donor and if it is a medium both it can act as acceptor and donor okay so we will see here o2 is having an oxidation state is zero so here so as the electronegativity of both the compounds is equal so oxidation state is zero and the electronegativity is same for both.

01:36 So there are loan paid of electrons for both the oxygens.

01:42 So it can be acts as acceptor and as well as donor.

01:52 Okay.

01:53 So as it is having loan paid of electrons and as it is having zero electronic configuration, it can accept and it can donate electrons.

02:03 And the second one is here plus 4 is the oxidation state for carbon and minus 2 is oxidation state for carbon oxygen...
