Answer:

See below.

Explanation:

The type of attractive force that must be overcome in order to melt the following substances in their solid state:

  • Xenon: London dispersion forces (LDF) or what is called Van der Waals forces. Xenon is an nonmetal element.
  • Hydrogen iodide: Dipole-dipole interactions. #HI# is a polar molecule that will form molecular solid.
  • Graphite: Covalent bonds. Graphite is an atomic network where carbon atoms are linked to each other through covalent bonds.
  • Barium Oxide: Ionic bonds. Barium oxide is an ionic compound that will form an ionic solid where ions are linked to each other through ionic bonds.
  • Ethanol: Hydrogen bonds. Ethanol is a polar molecule that will form a molecular solid and the main interaction is the hydrogen bonds in addition to the LDF.
