Why does ##HBr## have a higher boiling point than ##HCl##?

As a physical scientist, you really should quote these boiling points, these physical data.

##HBr## is a larger, more polarizable molecule than ##HCl##. There should be a greater degree of dispersion forces, forces between molecules, operating in the ##HBr## molecule, and thus the higher boiling point is observed.

Hang on, the boiling point of ##HF=19.5 “”^@C##, higher than those of ##HCl## and ##HBr##. Doesn’t this blow my proposal out of the water?
