I swear chemguide is basically why I passed my A-levels

Without it, I'd be doing sociology or retail assistant

i thought it was something to do with the fact that alcohols with longer chains (carbon bonds) need more energy to be broken and thus more energy is released?

and thanks for the link

No, this is completely illogical.

The energy released is due to the formation of strong carbon=oxygen double bonds in carbon dioxide. The more carbon in the original compound the more carbon dioxide is formed and therefore the more the energy that is released.
