Chapter 11, Problem 11.117QP

For the hydrogen halides and the noble gases, we have the following boiling points:

Halogen Family, °C	Noble Gases, °C
HF, 19	Nc, −246
HCl, −115	Ar, −186
HBr, −67	Kr, −152
HI, −35	Xe, −108

Account for the following:

1. a The general trend in the boiling points of the hydrides and the noble gases.
2. b The unusual boiling point of hydrogen fluoride.
3. c The observation that the hydrogen halides have boiling points that are significantly higher than the noble gases.
