Chem 162 Experiment #3: Intermolecular Forces Part II: Vapor Pressure and Enthalpy of Vaporization - GRADED A+

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 hand or using a drawing tool - not copy/pasted from a website). Part I: 26 points (report worksheet completed and handed in before leaving lab) Part II: 24 points (take-home report) Lab notebook pages: 10 pts Total: 60 pts By signing below, you certify that you have not falsified data, that you have not plagiarized any part of this lab report, and that all calculations and
