Answer 3

and what do you mean by "energy output". In terms of what? For fuel?

It only said 'energy output' so I have no idea.

The longer the chain, the more energy that is needed to unscramble the bonds (if you're referring to energy required to change phases).
But they are all primary alcohols, which require quite large amount of energy to dehydrate.
