In each of the following groups of compounds, identify the one with the largest heat of combustion and the one with the smallest. In which cases can a comparison of heats of combustion be used to assess relative stability?
(a) Cyclopropane, cyclobutane, cyclopentane
So, guys between cyclopropane, cyclobutane and cyclopentane, which do you expect to have the highest heat of combustion? Well, guys you might be thinking it's cyclopropane, right? Because we know it's under a lot of strain but that actually doesn't have the highest total heat of combustion, it has the highest heat of combustion per bond, okay? So, actually the one with the highest heat of combustion is going to be our cyclopentane, okay? let me know if you guys have any questions
