WitrynaFor oxidation/reduction in organic chemistry, we're just worried about whether electron density was gained or lost, not full transfer of electrons. So for carbon: if it gains a bond to a less electronegative group than itself (or loses a bond to a more electronegative one), those electrons count towards its oxidation state. ...
