Does HF or HBr have a higher boiling point?

H2O has the highest boiling point because it has the strongest/most IMFs. HF has a higher boiling point than HBr because of hydrogen bonds. 10.

Likewise, people ask, does HCL or HBr have a higher boiling point?

Bromine is a larger ion than chlorine and thus has stronger Van der Waals forces. Larger amounts of energy (a higher temperature) are required to break these interactions and so the boiling point of HBr is higher than HCl.

Additionally, why does h2o have a higher boiling point than HF? H2O has a higher boiling point than NH3 because (i) the H-bonds are stronger and (ii) it contains twice as many H-bonds. H2O has a higher boiling point than HF because it contains twice as many H- bonds, despite these being individually weaker. Only weak dispersion forces act in CH4 and CH3CH3.

Also know, why melting point of HI is greater than HF?

Although HI has a higher molecular mass than HF, the Van Der Waal's forces of attraction in HI are overpowered by intermolecular hydrogen bonding in HF. Hence, HF has a lower melting point than HI.

Why is HCl boiling point so low?

Out of HF, HCl, HBr and HI, which has the lowest and highest boiling point and why? Highest: HF due to H-bonding. Lowest: HCl because it has the smallest London force of all compound lacking hydrogen bonding. Note that the effect of hydrogen bonding is profound.
