Could anyone please tell me what would release the most heat energy methanol or propan-0-ol after burning and why. Thanks

Hey

I'm going to move this to the chemistry section as you're more likely to get some help there! :smile:

This is bond enthalpy change, but from what I can remember it's propanol, as both are exothermic reactions but there is a bigger difference in energy change (loss) in the combustion of propanol.

I'll have a go at making the Propan-0-ol with the Molymod kit tomorrow. ;P

Curiously, my Y10 class did this prac just this afternoon.

They found that the longer the chain length, the more energy was released per gram of fuel.
