Hydrogen fluoride has higher boiling point than hydrogen bromide ( HF 19.5 C HBr -66 C) because in hydrogen fluoride has two kinds of forces, one is hydrogen bonding and other is London dispersion forces. In Hydrogen bromide there are only london dispersion forces. These are weaker than hydrogen bonds therefore HF has the higher boiling pint.
Hydrogen fluoride (HF) has a higher boiling point than hydrogen bromide (HBr) as a result of hydrogen bonding between HF molecules, which is stronger than the Van der Waals forces present in HBr. The hydrogen bonding in HF results from the high electronegativity difference between hydrogen and fluorine atoms, leading to a stronger intermolecular attraction and higher boiling point.
Sodium fluoride has a higher boiling point than lithium fluoride due to stronger intermolecular forces of attraction between sodium and fluoride ions in sodium fluoride compared to lithium and fluoride ions in lithium fluoride. This stronger bond requires more energy to break, leading to a higher boiling point for sodium fluoride.
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.
Hydrogen fluoride (HF) is a gas at room temperature, but does have a higher boiling point than hydrogen chloride (HCl). Flourine is more electronegative than chlorine, so the HF molecule is more polar than the HCl molecule. This makes them more strongly attracted to one another (somewhat in the manner of magnets) and boiling a substance involves overcoming that intermolecular attraction.
The small size and high electronegativity of Fluorine is responsible for high polarity in HF molecules this high polarity is responsible for strong hydrogen bonding with in HF molecules so high amount of heat is required to convert the liquid HF into gaseous state and hence it has high boiling point as compare to HCl.Polar.

The two hydrogen-oxygen bonds in a water molecule allow it to form more hydrogen bonds with adjacent molecules than hydrogen fluoride can with its one hydrogen-fluorine bond. As a result, water has a stronger attraction between molecules.

Hydrogen fluoride (HF) has a higher boiling point than hydrogen chloride (HCl) because HF molecules are polar, allowing them to form stronger hydrogen bonds compared to the dipole-dipole interactions in HCl. This results in a stronger intermolecular attraction in HF, requiring more energy to overcome and hence a higher boiling point.
Boiling point of NH3: -33,34 0C Boiling point of NF3: -129,1 0C The boiling point of ammonia is higher.
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.
Boiling point of HCl: -85,1 0C. Boiling point of HF: 19,5 0C.
Because of hydrogen bonding. Oxygen, nitrogen, and fluorine have a high boiling point.
Hydrogen bonds themselves do not have boiling points, as they are not substances that can boil. However, the strength of hydrogen bonds influences the boiling points of substances that form hydrogen bonds. Stronger hydrogen bonding generally leads to higher boiling points, as more energy is required to overcome the intermolecular forces holding the molecules together.
