Homework Equations

None, as far as I know

The Attempt at a Solution

This is probably way more simple than I'm assuming it to be...but I'm not sure how to tell what IMF's each compound has. My teacher said that everything at least has London Dispersion Forces, so I know how to figure that out. I have no problem finding dipoles, or determining if something is a hydrogen bond. How do you know if something is an ionic crystal or network solid? That's where I'm lost. Thanks!

Like, for example, KMnO4. How would I go about determining the forces present?

Nevermind, we went over this in class, and I understand it much better now.
