$HF > HCl > HBr > HI :$ Boiling point

Vedclass · Answer

(C) The correct order for boiling points of hydrogen halides is $HF > HI > HBr > HCl$. $HF$ has the highest boiling point due to strong intermolecular hydrogen bonding. For the remaining hydrogen halides $(HCl, HBr, HI)$,the boiling point increases with increasing molecular mass due to stronger van der Waals forces of attraction. Therefore,the order given in option $C$ is incorrect.
