. . Review: How to determine which weak forces are exhibited: Lone atoms can only exhibit London Forces (LF) All molecules exhibit London Forces Is the molecule polar? If yes, it can exhibit dipole-dipole forces dip-dip) Does molecule have -X-H pattern where X-F.0 or N? If yes it can exhibit hydrogen bonding (1-bonding) If a molecule exhibits hydrogen bonding, it will also exhibit dipole-dipole forces 1. State what kinds of intermolecular forces that the following molecules can exhibit in pure-form solids and liquids. Use abbreviations shown in bold above, A) CH.NH ethylamine B) Xe xenon C) H hydroiodic acid D) C | ethane
