8. The cyclic voltammogram (CV) of the antiobiotic chloroamphenicol (abbreviated RNO2) is shown below. The first cathodic scan goes from 0 to -1.0V: the first cathodic wave, A, is from the reaction RNO2 4e +4H -RNHOHH20. Peak B in the reverse scan could be assigned to RNHOH - RNO 2H +2e. In the second cathodic scan from +0.9 to -0.4V, the new peak C appears. Write a reaction for peak C - and explain why peak C was not seen tin the initial scan.
