1. Draw the Lewis dot structure for methanol, CH3OH. Is this molecule polar? What is its dipole moment? In what molecular direction does the dipole point. Draw or illustrate this. Compare and contrast methanol with ethane, C2H6. Compare and contrast their intermolecular forces of attraction that operate between molecules in the bulk liquids. Illustrate these. Look up and explain their differences in boiling points.
Draw the Best Lewis Dot Structure Is it polar or nonpolar. Is it predominant intermolecular force (H-bonding, dipole-dipole forces, dispersion forces,) Answer the questions above for CO2, CH3OH, Br2, HF, CF2H2, NH3

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...
