Which is the weakest IMF?

• Dipole-Dipole

• Ion-Dipole

• Hydrogen Bonding

• Dispersion

What type of IMF does HF experience?

• Hydrogen Bonding

• Dipole-Dipole

• Dispersion

Answer explanation

Hydrogen chloride molecules experience dipole-dipole interactions, and hydrogen fluoride molecules have an H-F bond and so experience hydrogen bonding. (They also both experience London dispersion forces.) Therefore, hydrogen chloride experiences weaker intermolecular forces and has a lower boiling point.

Is CH₄ polar or nonpolar?
(Does it have a dipole moment?)

• Polar

• Nonpolar

Answer explanation

Hydrogen chloride molecules experience dipole-dipole interactions, and hydrogen fluoride molecules have an H-F bond and so experience hydrogen bonding. (They also both experience London dispersion forces.) Therefore, hydrogen chloride experiences weaker intermolecular forces and has a lower boiling point.
