Explain the following order of the boiling point (° C)
HF (19.5)> HCl (-85.1) <HBr (-66.8) <HI (-35.4)
b) Explain the following order of connection distance (pm):
HF (92) <HCl (127) <HBr (141) <HI (161)
The Attempt at a Solution
a) HF does hydrogen bond, and the others make ionic linking.
b) The lower the atomic mass, the higher the boiling point
