# Is a combustion necessarily a redox-reaction or can there be exceptions?

I have a feeling that I have heard of an exception - either based on the material or the oxidizer.

• I wouldn't think of combustion as necessarily a redox reaction. For instance burning methane doesn't seem like a redox reaction to me. – MaxW Oct 27 '17 at 20:43
• @MaxW It kind of is though. You're oxidizing a methane in a relatively uncontrolled setting. You might also consider a putative methane fuel cell which certainly suggests a redox. Still, I agree that it's usually best not to think of combustion in redox terms. There's not much to be gained even if it is a redox reaction. – Zhe Oct 28 '17 at 2:12
• @Zhe When I learnt redox reactions at school, we took the detour via combustion reactions (of magnesium, mainly) to reach the concept. – Jan Oct 28 '17 at 5:36
• @Enthuziast That's not the way things work. Feelings are not studied in chemistry. Bring us an example, then we'll see. Short of that, it's nonsense. – Ivan Neretin Oct 28 '17 at 8:59
