so what does "dissolve" mean? does it mean that the compound is broken up ( like NaCl getting ripped apart into individual ions) or can it be polar molecules being seperated from their structure (ie- no more intermolecular attractions)

Sure.
Sugar is an example.
It doesn't ionize when it dissolves in water.
If you look at a structure like http://dl.clackamas.cc.or.us/ch106-07/im…
you can see that a sugar is a chain of H-C-OH units.
The -OH portion of the molecule is polar just like it is in water.
The δ- O atom of the sugar can attract the δ+ H of a water molecule.
This decreases the attractions between sugar molecules themselves allowing them to form the individual solute molecules.
