These are much stronger than dispersion forces and so HF has an anomalously high boiling point. Cl and Br are not as electronegative as F: the dispersion forces in HCl and HBr are more significant than the dipole-dipole forces as can be evidenced by the order of boiling points HF > HBr > HCl.

Why does HF have a higher boiling point than HCl and HBr?

These are much stronger than dispersion forces and so HF has an anomalously high boiling point. Cl and Br are not as electronegative as F: the dispersion forces in HCl and HBr are more significant than the dipole-dipole forces as can be evidenced by the order of boiling points HF > HBr > HCl.

Which of the following has lowest boiling point HF HCl HI HBr?

HCl
HCl has the least boiling point due to the small dispersion intermolecular forces. HCl < HBr < HI < HF.

Which has higher boiling point HF or HCl?

a) The intermolecular bonding for HF is van der Waals, whereas for HCL, the intermolecular bonding is hydrogen. Since the van der Waals bond is stronger than hydrogen, HF will have a higher boiling temperature.

Why does HCl have a lower boiling point than HF and HBr?

Bromine is a larger ion than chlorine and thus has stronger Van der Waals forces. Larger amounts of energy (a higher temperature) are required to break these interactions and so the boiling point of HBr is higher than HCl.

What is the boiling point of HF?

67.1°F (19.5°C)Hydrogen fluoride / Boiling point

Which has a higher boiling point HF or HBr?

HF has the highest boiling point this is followed by HI, then HBr with HCl having the lowest boiling point of the four molecules. This is because HF is able to form Hydrogen bonds whereas the other three molecules are unable to do so because their electronegativity is not large enough to create a sufficient dipole.

Which has higher boiling HBr or HF?

Therefore, HF exists in the liquid state, and HI, HBr, and HCl exists in the gaseous state. > We can conclude, the order of boiling point followed is HF > HI > HBr > HCl.

What is the boiling point of HBr?

-86.8°F (-66°C)Hydrogen bromide / Boiling point

Which has the higher boiling point HBr or HF?

Why boiling point of HCl is?

However, the principle intermolecular force that operates between hydrogen chloride molecules is hydrogen bonding; i.e. δ+H−Clδ− . The dipoles line up in the bulk phase, and this constitutes a potent intermolecular force…… hence the respective boiling points.

What is the boiling point for HBR?

251.6°F (122°C)Hydrobromic acid / Boiling point

Does HCl have a high boiling point?

-121.1°F (-85.05°C)Hydrogen chloride / Boiling point

What is the boiling point of HF and HBr?

The boiling points of H F,H C l,H Br and H I follow the order H F > H I > H Br >H C l. HF is hydrogen bonded, thus has highest boiling point, and it is liquid at or below 19 oC. The remaining hydrogen halides are gaseous and their boiling points depend on the van der waal’s forces.

Why does HF have a higher boiling point than HCl?

Due to hydrogen bonding, HF shows highest boiling point. Therefore van der Waals’ force decide the boiling point. Larger the size or molecules mass, greater is the van der Waals’ forces. Hence, higher is the boiling point. ·.· van der Waals’ forces is more for HI than HBr, which is in turn is more than HCl.

Which hydrogen bond has the highest boiling point?

HF is hydrogen bonded, thus has highest boiling point, and it is liquid at or below 19 oC. The remaining hydrogen halides are gaseous and their boiling points depend on the van der waal’s forces. Larger the size (or molecular mass), greater are the van der Waal’s forces, hence higher is the boiling point.

Which force is responsible for boiling point of HCl?

>Talking about the boiling point, it depends upon the hydrogen bonding present between the molecules. >Now, if we consider the above molecules, i.e. HI, HBr, and HCl. In these molecules, the dominating interactions would be van der Waals forces.
