Hydrogen halide with the highest boiling point is:

A$$HF$$
Correct Answer
B$$HBr$$
C$$HCl$$
D$$HI$$

Solution

This is because of the presence of the H−bonding in HF, whereas others do not have H−bonding, so these can not associates as strongly as the HF,
so here the bonding of HF is strongest among all the HX, due to stronger HF bond.

−−−−−HF−−−HF−−−HF−−− (showing hydrogen bonding in HF molecules)
A hydrogen bond is the electrostatic attraction between polar groups that occurs when a hydrogen (H) atom bound to a highly electronegative atom such as nitrogen (N), oxygen (O) or fluorine (F) experiences attraction to some other nearby highly electronegative atom. Hydrogen halide with the highest boiling point is HF.
