1. van der Waals: compounds with vdW forces between molecules tend to have low melting and boiling points. This is because the vdW forces are relatively weak and require little energy to break the bonds. Soluble in non-polar solvents.
2. Permanent dipole attractions: have higher melting and boiling points than compounds with vdW forces as more energy is required to break their bonds because they are stronger. As they are polar they are soluble in polar solvents.
3. Hydrogen bonding: have high melting and boiling points owing to their strong intermolecular forces. As they are polar, they are soluble in polar solvents, such as water.
Like dissolves like, so polar compounds are soluble in polar solvents and vice versa.
