Consider the molecules H2O, H2S, H2Se, and H2Te. Which do you expect to have the highest boiling point, and why?
a. H2O, because it experiences hydrogen bonding.
b. H2S, because it dissociates and forms ions.
c. H2Se, because it experiences ion-dipole forces.
d. H2Te, because it has the most electrons to form a dipole.
