How do polar solvents dissovle polar compounds?
The molecules move and slip easily amongst each other, spreading out and mixing.

How do nonpolar solvents dissovle nonpolar compounds?
The molecules move and slip easily amongst each other, spreading out and mixing.
Negative ends of solvent molecules bind to positive ends of solute molecules; Positive ends of solvent molecules bind to negative ends of solute molecules
