molar heat of combustion (1 Viewer)

why is it that with primary and secondary alcohols, the one with the hydroxyl positioned at the end has a HIGHER molar heat of combustion
whereas if the hydroxyl group was positioned in the middle of the molecule, its molar heat of combustion is lower

i think it's got something to do with it being more reactive at the end of the molecule... I really have no idea sorry!!!

I'm guessing that it could have something to do with the accessibility of the oxygen. -OH sitting at the end is to the extreme outer of the molecule, meaning combustion will be easier...I think.

I don't know. Where's Dreamerish?
