2. Identify the strongest type of intermolecular forces in acetone, ethanol, water and hexane. (Structures listed on page 15.) Experiment 2 Intermolecular Forces There are three general types of intermolecular forces. All substances exhibit London Dispersion Forces (LDF), and they are generally the weakest of the three types. These London forces are due to the attractions between small, temporary dipoles that arise from the constant, random movement of the electrons in a substance. As molar mass increases, the size of...

The gases CO,(9) and NH, (9) can be liquefied at 20°C by compressing them to sufficiently high pressures. A student claims that NH,) can be liquefied at a lower pressure than C0,G) can be liquefied. Which of the following is the best justification for this claim? A) At 20°C, the average speed of NH3 molecules is greater than that of CO, molecules because NH, molecules have less mass than Co, molecules have. (B) Co, is a nonpolar molecule that has...
