Laboratory Section:

1. Indicate whether the each of the three substances below is polar or nonpolar, then list the intermolecular attractive forces that must exist for each substance when in the liquid phase. Note: Use the hint if you have difficulty drawing the Lewis structure of each compound. NOTE: IMAF means intermolecular attractive force.
