Question

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⁺, SO₄^2-, NO₂^-, NO₃^-, HS^-, CH₄, and Fe³⁺

Answer 1

element in its maximum oxidation state will be electron acceptor only.if element in its lowest oxidation state will be electron doner if it lies between highest O.S and lowest O.S then can be both electron acceptor and electron doner but not at the same instant
