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.
Why HF has a higher boiling point than HBr?
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.
Is the boiling point of hydrogen higher or lower than fluorine?
The boiling point of hydrogen is lower than that of fluorine. Hydrogen is a gas at room temperature and pressure, with a boiling point of -252.87°C, while fluorine is a gas at room temperature and pressure, with a boiling point of -188.12°C.
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.
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.

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 the boiling point of water higher than the boiling point of Ethan?
The boiling point is the temperature at which a liquid will change into a gas. This happens when the molecules have enough energy to break the bonds holding them in close proximity. Since water molecules have a stronger attraction to each other than ethane molecules have for each other, water needs to be heated to a higher temperature to break these bonds.
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.
How can the temperature in the autoclave go above boiling temperature of 212 F?
The temperature in an autoclave can go above the boiling temperature of 212°F by increasing the pressure inside the autoclave. As pressure increases, the boiling point of water also increases. This allows the autoclave to achieve temperatures higher than the standard boiling point of water.
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.
HF HCl boiling temperature?
Boiling point of HCl: -85,1 0C. Boiling point of HF: 19,5 0C.
Is Boiling is the maximum temperature a substance can reach?
Boiling is the temperature at which a substance changes from a liquid to a gas. It is not necessarily the maximum temperature a substance can reach, as some substances can be heated to higher temperatures without boiling.
