Chem SDI question

Hi guys,

Can anyone explain why the fuels with lower oxidation states release more heat upon combustion??

[Esoteric]

All combustion reactions are oxidation reactions (Fuel is oxidised by O2), and oxidation results in an increase in oxidation state (or higher oxidation number).
Therefore, logically if a fuel has a low oxidation state it has a potential to be oxidised to a greater extent (or has greater potential to increase its oxidation state):. can produce more energy upon oxidation/combustion.

Hope that helps.
