What IMF's exist in heptane? why?
-
what types of imf's are there? what causes these imf's?
-
yes
-
yes
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

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?

Awesome, well done! And perfect reasoning!
