adv question, someone is stuyding very hard 😉
they have lower B.P.elz787 said:
At first thought, one might think that the boiling points of the alkenes would be higher than the cycloalkanes. The alkenes are larger and they can experience a dipole-dipole interaction. But, because of the greater symmetry of cycloalkanes, they are able to pack more tightly together which increase the vander Waals attractions. This increase in the vander Waals attractions increases the boiling points of the cycloalkanes.

Didn't he ask about alkanes and not alkenes? Forgive me if I am missing something; my knowledge of ochem is very limited, but I think the a vs e makes a big difference.
Wouldn't it depend on how long of a carbon chain/ring you are comparing it to?
I'm sure a cyclohexane is more stable than a hexane, but if you comparing a 17 chain carbon versus some monsterous (if even possible) cycle 17 carbon structure; I would think the 17 chain carbon would have a lower bp point since it would stack better than the huge cycle carbon monster

one can always find an exception but the original question was a valid one. 😉
