  1. NaCl should be the highest because NaCl is an ionic compound and those boil at higher temperatures due to breaking the lattice energy of the crystal etc. The lowest should be F2 since there is no hydrogen bonding involved. Both HCl and HF have higher boiling points due to hydrogen bonding and should fall between the two extremes. I would expect HCl to have a higher boiling point than HF due to HCl having a higher molar mass than HF.
