Hmmm...not quite the answer I think ni_bartel was looking for.

Can you tell us what types of IMFs you have learned about?

Dipole-Dipole, London Dispersion, Hydrogen Bonding forces

Ok good!  Now, can tell what types of molecules or species interact in each of those types?  Which category does Heptane fit into?

Well Dipole Dipole forces exist between neutral polar molecules, but Heptane is nonpolar. Heptane does not contain hydrogen bonding  forces since no H atoms bond with F, O, or N. So I guess Heptane would have london dispersion since it contains non-polar molecules. Would that be correct?
