On part (c) of 3F.5 in the textbook, it asks if CHI3 of CHF3 has a higher boiling point. I assumed it was CHF3, as there is a larger difference in electronegativity between C and F than C and I, therefore the bonds would be stronger and harder to boil in CHF3. However, the answer key says that CHI3 has a higher boiling point...can someone explain why?

Although C and F have the larger difference in electronegativity, CHI3 is simply larger, so it has a higher boiling point.
