Vedclass · Answer

(A) The boiling point of hydrogen halides depends on the intermolecular forces of attraction. In $HF$ molecules,the high electronegativity and small size of the fluorine atom lead to the formation of strong intermolecular hydrogen bonding. This results in a significantly higher boiling point compared to other hydrogen halides $(HI, HBr, HCl)$,where only weaker van der Waals forces are present. Thus,the order is $HF > HI > HBr > HCl$.

The variation of the boiling points of the hydrogen halides is in the order $HF > HI > HBr > HCl$. What explains the higher boiling point of hydrogen fluoride?
