In the previous lab, you learned how to identify polar and nonpolar molecules. You also learned how to draw
hydrogen bonds; one of the Intermolecular Forces (IMFs). IMFs affect properties of substances. In this lab,
you assess how IMFs affect evaporation/boiling of a liquid to a gas. Consider that this vaporization process
involves breaking IMFs with neighboring molecules and answer the following question.
The strength of the intermolecular forces of HF is significantly stronger than the strength of the
intermolecular forces of HCI. Which of the following is TRUE?
HF forms hydrogen bonds between molecules and HCI forms dipole-dipole forces.
HF is larger than HCI.
HF forms dipole-dipole forces between molecules and HCI forms only London dispersion forces
between molecules.
HF forms ion-dipole forces between molecules and HCI forms hydrogen bonds between molecules.
HF is polar, but HCI is non-polar.
