3 cards from this section. Quick, good the night before a test.
Define intermolecular forces in one sentence.
Think about the forces existing between molecules as opposed to inside them.
What is an example of a substance exhibiting dipole-dipole forces?
Recall polar molecules where positive and negative ends attract.
What is the strongest type of intermolecular force?
Think about which forces involve hydrogen with highly electronegative elements.
True or False: London dispersion forces are present in all molecules.
Consider if all molecules have some form of electron cloud.
Describe a situation where you would compare the boiling points of two substances, one with strong hydrogen bonds and another with only London dispersion forces. What factors would you consider?
Think about why we need heat to change states.
A liquid has a lower viscosity than another; deduce which intermolecular forces might be weaker in the less viscous liquid and explain.
Consider how viscosity relates to the movement of molecules.
