Use the electron counting method to determine the oxidation state C2. Oxid # for H is +1, O is -2. so 2C+4(1)-2(-2)=0. There is no oxidation number for compounds. I took an educated guess as to what this compound is and got it right: sucrose. The oxidation number of each atom can be calculated by subtracting the sum of lone pairs and electrons it gains from bonds from the number of valence electrons. C6H6: -1. What is the oxidation number of C in C2H4O2? O.S of H= +1. O has an oxidation of -2 when it's not by itself. Thus, the oxidation state of carbon is glucose, C 6H 12O 6, is zero and the oxidation state of carbon in ethanol, C 2H 6O, is –4. I am also confused because H and O occur in multiple places, how can I decide whether to say things were oxidized and reduced? I'm not sure what I am doing wrong or a another way to go about it.
