Intermolecular Forces Quiz

What are intermolecular forces?

• Forces between atoms within a molecule

• Forces between ions within a molecule

• Forces between atoms, ions, or molecules that hold them together

• Forces between molecules within a substance

Which type of intermolecular force is present in nonpolar molecules?

• London dispersion forces

• Dipole-dipole interactions

• Hydrogen bonding

• Ionic interactions

What causes London dispersion forces?

• Motion of electrons within an atom or molecule

• Permanent dipoles in polar molecules

• Large difference in electronegativity between atoms

• Attraction between metal and nonmetal atoms

Which factor increases the strength of London dispersion forces?

• Decrease in the number of electrons

• Increase in the size of the molecule

• Decrease in the polarizability of the molecule

• Lack of pi bonds

What is the strongest intermolecular force that occurs between polar molecules (no F, O, N bonded to H)?

• London dispersion forces

• Dipole-dipole interactions

• Hydrogen bonding

• Ionic interactions

Which type of intermolecular force is strongest?

• London dispersion forces

• Dipole-dipole interactions

• Hydrogen bonding

What is the name for the attraction between molecules that contain H-N, H-O, or H-F bonds?

• London dispersion forces

• Dipole-dipole interactions

• Hydrogen bonding

• Ionic interactions
