AP Chemistry - Unit 3 - Thou Shall Not Forget

Front

What type of alloy is formed when the atomic radii of the constituent elements are similar?

Back

Substitutional alloy.

Front

List the four types of intermolecular forces from weakest to strongest.

Back

London dispersion, dipole-dipole, hydrogen bonding, ion-dipole.

Front

How are pressure (P) and volume (V) related in a gas?

Back

Inversely related.

Front

What intermolecular forces are present in PCl3?

Back

London dispersion and dipole-dipole.

Front

What type of bonds break when a molecular solid melts or boils?

Back

Intermolecular bonds.

Front

Define substitutional alloy.

Back

An alloy where one element replaces another in the crystal lattice due to similar atomic radii.

Front

What is the strongest type of intermolecular force?

Back

Ion-dipole.

Front

Explain the concept of London dispersion forces.

Back

Weak intermolecular forces arising from temporary dipoles in molecules.

Front

What is the relationship between temperature and kinetic energy in gases?

Back

Directly proportional; as temperature increases, kinetic energy increases.

Front

What is dipole-dipole interaction?

Back

Attraction between polar molecules due to their permanent dipoles.
