Question

what is the oxidation state of C in C6H12O6?

Answer 1

Therefore, for glucose, we have twelve H at +1 each, six O at -2 each. This sums to +12 for the H and -12 for O, which means the six carbons are at zero. For CO2, we get -4 for the O so the C must be +4. CO2 is the highest oxidation state for carbon, meaning it is the most oxidized form.
