Which has a higher boiling point hf or hcl? a) The intermolecular bonding for HF is van der Waals, whereas for HCL, the intermolecular bonding is hydrogen. Since the van der Waals bond is stronger than hydrogen, HF will have a higher boiling temperature. … Since the hydrogen bond is stronger than van der Waals, HF will have a higher boiling temperature.
Why boiling point of HCl is lowest and HF is highest? HF shows H-bonding possess a higher boiling point or less volatile nature. HCl has the least boiling point due to the small dispersion intermolecular forces.
Why does HF have a higher boiling point? – The other halogens are not as electronegative and so other hydrogen halides cannot form hydrogen bonds between molecules. Only London Forces are formed. – Therefore more energy is required to break the intermolecular forces in HF than the other hydrogen halides and so it has a higher boiling point.
Which of the following has highest boiling point HF HCl? If we talk about the HF, it has strong hydrogen bonding, thus has the highest boiling point. > Therefore, HF exists in the liquid state, and HI, HBr, and HCl exists in the gaseous state.
