Vedclass · Answer

(B) The boiling point of hydrogen halides depends on the intermolecular forces present. $HF$ exhibits strong intermolecular hydrogen bonding,which results in a significantly higher boiling point. For the remaining hydrogen halides ($HCl$,$HBr$,$HI$),the boiling point increases with increasing molecular mass due to the increase in the strength of Van der Waals forces. Since $HCl$ has the lowest molecular mass among these,it has the weakest Van der Waals forces and therefore the lowest boiling point. The order of boiling points is: $HCl < HBr < HI < HF$.

Which of the following compounds has the lowest boiling point?
