Chem 162 Experiment #3: Intermolecular Forces 
Part II: Vapor Pressure and Enthalpy of Vaporization 
PURPOSE (4 pts) 
The purpose is to measure the enthalpies of vaporazation of pentane, diethyl ether, butanone, and 2-butanol. For 
each of these molecules, a portion of the enthalpy of vaporization is due to dispersion forces (all molecules have 
dispersion forces) and the other to a polar component. In the boxes provided below, draw the structural formula for 
each molecule (should be drawn by h...
