HI has a higher boiling point because of the dipole-dipole Intermolecular forces as well as the dispersion forces, which become more evident with molecular weight, which will dominate over the dipole-dipole forces, so HCl has a lower boiloing point.

-84°C for HF -114.2°C for HCl So, HCl has a lower boiling point because the HF has hydrogen bonds attracting the molecules and so therefore has a higher heat of vaporization.

The boiling point of hydrogen flouride (HF) is the highest at 19.5oC. The boiling point of hydrogen bromide (HBr) -66.38oC and the boiling point of hydrogen chloride (HCl) is -85.1oC.

Why is the boiling point of HI higher than HBr?

This is to do with the intermolecular forces in the two compounds. There are no hydrogen bonds between the molecules of either compound, since Br and I are not electronegative enough to polarise the molecules sufficiently. But since HI molecules contain more electrons than HBr, there are increased van der Waals forces in HI. For the same reason HBr has a higher boiling point than HCl, but HF has a higher boiling point than HCl, HBr or HI because of hydrogen bonding.


Which has a higher boiling point HI or HF?

HF is electronegative compared to O2. HF has delta plus and delta minus creating a dipole moment, it is a polar molecule therefore it has a higher boiling point. O2 which is symmetrical and non polar (looks like O=O) and therefore has no dipole moment.


Why does hydrogen iodide have a higher boiling temperature than hydrogen bromide?

There is no hydrogen bonding in HBr and HI. The intermolecular forces are London dispersion forces- HI has more electrons, so more instantaneous induced dipole-dipole interaction- more intermolecular force- and therefore a higher boiling point.

Which is most polar HBr HCl HI?

The polarity of a bond increases with the increment of the difference of electronegativity between the corresponding two atoms. Therefore HCl is most polar whereas HI is the weakest among the given.
