Summary:
- Molecular compounds display a wide range of physical properties due to the different types of intermolecular attractions.
- The melting and boiling points of molecular compounds are generally quite low compared to those of ionic compounds.
- Ionic compounds do not conduct electricity in the solid state because of their rigid structure, but conduct well when either molten or dissolved into a solution.
- Substances that exhibit hydrogen bonding or dipole-dipole forces are generally water soluble, whereas those that exhibit only London dispersion forces are Generally insoluble.
