Unformatted text preview: Name: ___________________________________ Intermolecular Forces – Study Guide CH101 section 11.3 in the textbook Dipole‐dipole Interactions Dipole‐dipole interactions are forces of attraction between molecules which are permanently _______________. Explain briefly what is meant by the term dipole, and why would they be attracted to one another. Watch video tutorial on Blackboard example: Which of the following molecules would be expected to have significant dipole‐dipole interactions in the liquid state? CO N2 NH3 CO2 CCl4 HI Hydrogen Bonding Hydrogen bonding occurs in liquids when hydrogen is bonded directly to one of the elements ______, ______, or ______. Hydrogen bonding is the _________________ (strongest, weakest) of the main types of intermolecular forces. Watch video tutorial on Blackboard example: Which of the following molecules would be expected to undergo hydrogen bonding in the liquid state? CH3OH H2S CH3F CH3NH2 Dispersion Forces or London Forces While dipole forces are present in all liquids, they are the most significant type of intermolecular force only in liquids that are normally ___________________ (polar, nonpolar). Explain briefly what causes an instantaneous dipole to be formed. example: In which of the following molecules would dispersion forces be the primary type of intermolecular force? CO N2 NH3 CO2 CCl4 HI Ion‐dipole Interactions Ion‐dipole interactions are the result of an electrostatic attraction between _____________ and ____________________________________.
