Vedclass · Answer

(C) The boiling point of hydrides of halogens depends on two main factors: intermolecular hydrogen bonding and van der Waals forces. $HF$ has the highest boiling point due to strong intermolecular hydrogen bonding. For the remaining hydrides ($HCl$,$HBr$,$HI$),the boiling point increases with increasing molecular mass due to the increase in the magnitude of van der Waals forces. Thus,the order is $HI > HBr > HCl$. Combining these,the overall decreasing order of boiling point is $HF > HI > HBr > HCl$.

Identify the correct decreasing order of boiling point for hydrides of halogens.
