To finish this assignment, you should pick up the IMF graphic organizer in class and fill it out to create focused notes for the week. Some notes are added below to help you understand how to fill out the organizer.
Compare and contrast the different types of forces in these three boxes
Make yourself a table. What type of bonds does each of these covalent compounds make
How does each of the intermolecular forces affect the properties of a substance. High or Low is fine.
Make sure you have an explanation or a diagram that explains why oil has good adhesion (sticks to itself) or geckos can stick to ceilings. Remember dispersion forces are tiny, but alot of dispersion forces can really add up.
