What is the order of the boiling points (from lowest to highest) for the hydrogen halides?

HF>HI>HBr>HCl is the sequence in which the boiling points of HCl, HBr, and HI are found.
Because HF and hydrogen are hydrogen linked, it has the maximum boiling point and is a liquid at or below ${19}^{\circ }\mathrm{C}$. The remaining hydrogen halides are gaseous, and the van der Waal forces determine their boiling points. The van der Waal forces increase with increasing size (or molecular mass), raising the boiling point in the process.
