4 cards from this section. Quick, good the night before a test.
What are London Dispersion Forces?
Think about the movement of electrons.
Name one factor that affects the strength of LDFs.
Larger molecules have more of these.
Which of the following forces is the weakest type of intermolecular force?
Remember, they are weaker than the rest.
True or False: LDFs are only present in polar molecules.
Think about how universal these forces are.
Consider two molecules of equal mass but different shapes, one being a long chain and the other being round. Explain how their LDF strengths differ and predict their boiling points.
What does the shape tell you about their interaction?
Evaluate how increasing the molecular size from Cl2 to I2 affects the LDF strength and boiling points. Support your answer with molecular theory.
Think about how the electron cloud affects forces.
