Unformatted text preview: Justin Benson Jen Stam Jodi Smith CHM 113 LAB I nvestigation 21: What Causes I n te rmolecular Forces? I N TRODUCT ION: The goal of this lab was to find what causes intermolecular attractions in molecules and use the conclusions to decide what liquids the toy maker could use in his new toy. These liquids were required to attract and repel each other to form layers within the toy. We were to use a molecular model kit in order to build models of the different molecules listed. We were then required to use the models to decide what attractive forces between the molecules were occurring. The models were then used to show and explain the forces and attractions between the liquids that would exist together in the toys as layers.
