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.
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.
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.
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.
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.
Yes, hydrogen fluoride is an acid; a very dangerous one!Hydrogen fluoride is hydrofluoric acid.What hydrogen fluoride is:Hydrogen fluoride is a chemical compound that contains fluorine. It can exist as a colorless gas or as a fuming liquid, or it can be dissolved in water.When hydrogen fluoride is dissolved in water, it may be called hydrofluoric acid.Hydrogen fluoride also can be released when some other fluoride-containing compounds such as ammonium fluoride are combined with water.
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.

due to intermolecular hydrogen bonding
Because of hydrogen bonding. Oxygen, nitrogen, and fluorine have a high boiling point.
Hydrogen bonding
Since oxygen has a higher electronegativity than nitrogen, the hydroxyl radical is more polar than the amide radical, and hence, creates a stronger electrostatic attraction between molecules and consequently a higher boiling point.
Ethanol has hydrogen bond where as ether does not.
