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.
Examples are: HCl, HNO3, HF, HI.

with HCl the reaction is endothermic and homolysis of HCl does not occur as the effect follows free radical mechanism. The homolysis of HI occurs but the i radical forms iodine molecule and also it's activation energy is high.
No, a cup of water and a large soup pot of water will both boil at the same temperature, which is 100°C (212°F) at sea level. The boiling point of water is determined by the atmospheric pressure, so as long as the pressure remains constant, the boiling point will also remain constant.
To break down a Hi-Point 9mm, first ensure the firearm is unloaded. Then, follow the manufacturer's guidelines to disassemble the gun by removing the slide, barrel, and recoil spring. Be sure to clean and lubricate the components before reassembling the firearm.
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.
a) O2 would have a higher boiling point than N2 since it experiences London dispersion forces in addition to its higher molecular weight. b) SO2 would have a higher boiling point than CO2 due to its ability to form stronger dipole-dipole interactions and London dispersion forces. c) HF would have a higher boiling point than HI due to hydrogen bonding, which is stronger than the dipole-dipole interactions present in HI.
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.
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 is the strongest acid among HF, HCl, HBr, and HI. This is because the strength of an acid increases as the size of the atom bonded to hydrogen increases down the halogen group. HI has the largest atom size and the weakest halogen bond, making it the strongest acid.
NaI has the lowest boiling point at standard pressure because it is a molecular compound with weaker intermolecular forces compared to the other compounds listed, which are all ionic compounds. Ionic compounds generally have higher boiling points due to stronger electrostatic interactions between ions.
Hydrochloric acid (HCl) is considered the most volatile halogen acid compared to the other halogen acids such as hydrofluoric acid (HF), hydrobromic acid (HBr), and hydroiodic acid (HI). This is because HCl has a lower boiling point and higher vapor pressure, making it more likely to evaporate and form vapors at room temperature.
Examples are: HCl, HNO3, HF, HI.
HF = Hydrofluoric Acid HCl =- Hydrochloric Acid HBr = Hydrobromic Acid HI = Hydroiodic Acid .
HF > HCl > HBr > HI Hydrogen-bond strength is determined by the electronegativity difference; since fluorine has the smallest radius, it exerts the greatest attractive force over the H+ cation, creating the strongest bond.
Hydroiodic acid (HI) is an acid which contains the iodide anion. Likewise, hydrofluoric acid (HF) is an acid which contains the fluoride anion. HF is a weak acid, although HI (like HCl and HBr) is a strong acid.
In terms of acidity HI > HBr > HCl > HF
