What type(s) of intermolecular bonding do each of the structures contain? Do all Isomers have the same melting point/boiling point? Why or why not?

We were told to identify all the isomers of C4H8 and C4H6 and their mp/bp. I can't figure out how to find the intermolecular bonding these would have.

Well, there are 6 isomers of #C_4H_8#....and 5 isomers (I think) of #C_4H_6#

Explanation:

I leave this up to you to find them all.....

Because there are NO heteroatoms in either molecule, only dispersion forces operate, and thus the more linear isomers should be more involatile than the branched one, because the unbranched chains have greater operation for intermolecular interaction along their length....anyway you will have to look these up yourself.
