Purpose: The purpose of the lab was to investigate and demonstrate hydrogen bonding and London dispersion bonding in water and rubbing alcohol. Hypothesis: I believe water will have the greater surface tension because rubbing alcohol’s density is lower than water’s. Materials: * Water * Isopropyl alcohol (rubbing alcohol) * Pennies * Paper clips * Flasks * Cups or jars * Wax paper * Eyedropper Procedures: Part 1: Surface tension and vortex: * Fill
