For the hydrogen halides and the noble gases, we have the following boiling points:
Halogen Family, °C Noble Gases, °C
HF, 19 ……………………....... Ne, 246
HCl, 115 …………………… Ar, 186
HBr, 67 …………………….. Kr, 152
HI, 35 ……………………...... Xe, 108
Account for the following:
a. The general trend in the boiling points of the hydrides and the noble gases.
b. The unusual boiling point of hydrogen fluoride.
c. The observation that the hydrogen halides have boiling points that are significantly higher than the noble gases.
