Which of the following statements best describes dipole-dipole interactions?
Dipole-dipole interactions occur between two molecules when they have a partial positive and negative end, due to an unequal distribution of electrons.
Dipole-dipole interactions are the weakest intermolecular forces and are the primary forces responsible for the high boiling point of water.
Dipole-dipole interactions are temporary fluctuations in electron distribution that create temporary positive and negative ends in molecules.
Dipole-dipole interactions only occur in ionic compounds when cations and anions are attracted to each other.

Which of the following statements best describes London dispersion forces (also known as Van der Waals forces)?
London dispersion forces result from the attraction between oppositely charged ions in a crystal lattice.
London dispersion forces are the result of hydrogen bonding between molecules containing hydrogen atoms bonded to highly electronegative elements.
London dispersion forces are the weakest intermolecular forces and result from temporary fluctuations in electron distribution, creating temporary dipoles.
London dispersion forces occur when two molecules with permanent dipoles align in a way that maximizes their attractions.

Which of the molecule, HCl and HI, has the higher boiling point? What would be the likely explanation?
HI, since Iodine is more electronegative than Chlorine, so HI is a stronger dipole-dipole interaction than HCl.
HI, since Iodine is more electronegative than Chlorine, so HI is a stronger ion-ion interaction than HCl.
HCl, since Chlorine is more electronegative than Iodine, so HCl is a stronger ion-dipole interaction than HI.
HCl, since Chlorine is more electronegative than Iodine, so HCl is a stronger dipole-dipole interaction than HI.
