Vedclass · Answer

(C) $HF$ exhibits strong intermolecular hydrogen bonding,which results in a significantly higher boiling point compared to other hydrogen halides.For the remaining hydrogen halides $(HCl, HBr, HI)$,the boiling point is primarily determined by the magnitude of van der Waals' forces,which increase with an increase in molecular mass.Therefore,the order of boiling points is $HI > HBr > HCl$.Combining these,the overall decreasing order of boiling points is $HF > HI > HBr > HCl$.

The correct decreasing order of boiling point of hydrogen halides is
