  1. Intermolecular forces (IMF) Name: _______________________________________ What is happening here? What’s happening here?

  2. Intramolecular bond vs intermolecular force • … • … • … • … • Think of intranet… • ...

  3. Intramolecular bond vs intermolecular force • Intermolecular force is … • … • This is like the internet… • …

  4. Four kinds of intermolecular forces • Intermolecular forces In the order of weakest to strongest: • … • … • … • …

  5. Intermolecular forces • Professor dave • Without intermolecular forces… • The __________the imf the ________ the boiling point… WHY? • The ________the Imf the __________ the boiling point… why?

  6. What is a dipole? • Before we define each type of intermolecular force let’s define dipole. • Dipole – • in other words – Draw an example of a molecule with a dipole below:

  7. Defining each IMF: Dispersion Force • The dispersion force is also called • … • The dispersion force is … • … • … • The dispersion force is caused by… Draw a picture of helium with a dispersion force below:

  8. Defining each IMF: Dipole-Dipole force • Dipole-dipole force is an interaction __________________________________________ • A polar molecule has a ____________________________ • Examples:

  9. Defining Each IMF: Hydrogen bond • Hydrogen bond – not a bond, not a bond, _____________________, not a bond!!!!! • … • The following bonds (actual bonds) create a very strong dipole • … • … • … • … • ________________is a great example of hydrogen bonding in action!

  10. Defining Each IMF: Hydrogen Bonding • Draw a few pictures of substances hydrogen bonding:

  11. Defining Each IMF: Ion-Dipole Force • The Ion-dipole force is the ______________________ imf • … • This is why some __________ compounds will __________________________. • Draw a picture below:
