Understanding Intermolecular Forces Quiz

Which of the following molecules can form hydrogen bonds?

• Ne

• Ar

What is a key feature of molecules that exhibit London Dispersion forces?

• They must contain a hydrogen atom bonded to N, O, or F.

• They must be polar molecules.

• They can be either polar or nonpolar molecules.

• They must have a triple bond.

Which type of intermolecular force is the weakest?

• Hydrogen bonding

• London Dispersion forces

• Dipole-dipole interactions

• Ionic bonding

In which of the following pairs would you expect to find dipole-dipole interactions?

• Ne and Ar

• HCl and HBr

• NaCl and KBr

Which of the following statements is true about London Dispersion forces?

• They increase with the size of the molecules.

• They are only present in ionic compounds.

• They decrease with the increase in molecular size.

• They are stronger than hydrogen bonds.

What is required for a molecule to participate in hydrogen bonding?

• It must have a high molecular weight.

• It must contain a hydrogen atom bonded to nitrogen, oxygen, or fluorine.

• It must be a nonpolar molecule.

• It must have a carbon-hydrogen bond.

Which of the following molecules will exhibit the strongest dipole-dipole interactions?

• HCl

What is the main reason that London Dispersion forces exist?

• The movement of electrons creates temporary dipoles in molecules.

• The permanent dipole moments in molecules attract each other.

• The sharing of electrons between atoms.

• The transfer of electrons from one atom to another.

Which of the following is not a characteristic of hydrogen bonds?

• They are stronger than covalent bonds.

• They involve a hydrogen atom and an electronegative atom like N, O, or F.

• They contribute to the high boiling point of water.

• They play a crucial role in the structure of DNA.
