Listed below are the redox potential of “half reactions” of some reactions involved in electron transfer. Rank them according to the sequence of their position in transferring electrons from a high energetic state to a lower one.

Half reaction                                                                       E0’ (V)
Cytochrome c (Fe3+) + e-    ->? Cutrochrome c (Fe2+)     0.254
NAD+ + H+ + 2e-  ->? NADH                                             -0.324
Ubiquinone + 2H+ + 2e-   ->? Ubiquinol + H2                    0.045
FAD + 2H+ +2e- ?->      FADH2                                         -0.219
