why does SO2 have dipole dipole forces? i don't really understand the concept of dipole dipole forces or how you know when a molecule exhibits it so if someone could explain that would be awesome!

dipole moments are based on partial positive and negative ends of a molecule. You can determine through the electronegativity differences in the molecule. Since O is more electronegative than S, O has a partial negative charge and S has a partial positive charge. There is a dipole moment within the molecule. SO2 is also a polar molecule.

Also keep in mind that the dipole moment is a permanent dipole moment, meaning its polar.

Dipole-dipole usually exists between polar molecules. Thus, to determine, just draw out the lewis structure of the molecule and see if it's polar or not. To determine whether it's polar, you will need to find its dipole moment and its molecular shape.
