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.

Why hydrogen bromide has higher boiling point than hydrogen fluoride?
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.
How can the temperature in the autoclave go above boiling temperature of 212 F?
At higher pressure the boiling point is higher.
Which has a higher boiling point HI or HCl?
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.
Which has the higher temperature - boiling water or ice?
boiling water
Why c2h5oh has higher boiling point?
due to intermolecular hydrogen bonding

boiling water
The boiling temperature of water is so much higher than that of methane because water molecules are what?
Water is polar and is strongly hydrogen bonded.
Why water have higher boiling point then other substance?
Becuase the Hydrogen bonds keeps the water atoms from separating until a high temperature is reached.
Why c2h5oh has higher boiling point?
due to intermolecular hydrogen bonding
Which is hotter the boiling water or oil?
Boiling oil because it boils at a higher temperature
The boiling temperature of water is so much higher than that of methane because water molecules are?
d.polarWater molecules are polar covalent and therefore form attractions between the molecules called hydrogen bonds. Much of the heat that goes into raising the temperature of water to its boiling point goes to breaking the hydrogen bonds first.
Why higher boiling hydrocarbonates are distilled under vacuum condition?
because they decompose at higher temperature.. under vacuum they can be boiled at lower temperature than their boiling point
What is responsible for the high boiling point of water?
The greater the forces of attraction, higher the boiling point or the greater the polarity the higher the boiling point. Water having strong molecular forces between water molecules makes the force, this force holds one water molecule to the next. The inter-molecular forces between water are called hydrogen bonds. Hydrogen bonds are special type of dipole-dipole force that exists between an electronegative atom and a hydrogen atom bonded to another electronegative atom. It takes a lot more kinetic energy in an increased temperature to break the hydrogen bonds to free the water molecules as the gas making higher boiling points. Its ability to form Hydrogen Bonds with itself.
How does pressure affect boiling point?
The boiling point is that temperature when the SATURATEDvapor pressure of a liquidbecomes equal tothe surrounding pressure.Thus the higher the sorrounding pressure, the higher the boiling point.
