Why does HF have a higher boiling temperature than F?
Since the hydrogen bond is stronger than van der Waals, HF will have a higher boiling temperature. d) The atomic number for CL is greater than for F, so HF will have a higher boiling temperature.
What is the difference between HF and HCl?
c) The intermolecular bonding for HF is hydrogen, whereas for HCL, the intermolecular bonding is van der Waals. Since the hydrogen bond is stronger than van der Waals, HF will have a higher boiling temperature.
Why Hi has a higher boiling point than HCl?
Why HI has a Higher Boiling Point than HCl? The boiling point rises from HCl to HI. The increasing intensity of the van der Waals intermolecular forces is due to this trend, which coincides with the number of electrons in the molecules.
What is the intermolecular bonding of HF and HCl?
c) The intermolecular bonding for HF is hydrogen, whereas for HCL, the intermolecular bonding is van der Waals. Since the hydrogen bond is stronger than van der Waals, HF will have a higher boiling temperature. Click to see full answer.
Why boiling point of HF is higher than that of HCl?
For the given question we can say that the basic reason because of which the Boiling point of $ HF $ is greater than $ HCl $ is the presence of the greater the intermolecular forces. The greater the boiling point. HF has strong intermolecular forces, due to hydrogen bonding between HF and H.
Why is the boiling point of HCl less than of HF?
HF shows H-bonding possess a higher boiling point or less volatile nature. HCl has the least boiling point due to the small dispersion intermolecular forces.
Why does HF have a higher boiling point?
The reason is the presence of strong hydrogen bonding in the HF, as hydrogen intermolecular interactions are greater than the van der Waals forces. So, HF has a higher boiling point than the HI.
Why is HF boiling point higher than HBr?
The variation of the boiling points of the hydrogen halides is in the order HF > HI > HBr > HCl due to strong H-bonding in HF molecule, boiling point is highest for HF.
Which has stronger intermolecular forces HF or HCl?
Comments to the instructor: The strongest intermolecular force for HF is the hydrogen- bonding interaction. This is a stronger force than the dipole-dipole interactions between HI, HBr and HCl.
What is the boiling point of HF?
67.1°F (19.5°C)Hydrogen fluoride / Boiling point
Which has highest boiling point HF HCl HBr HI?
HF is hydrogen bonded, thus has highest boiling point, and it is liquid at or below 19oC. 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.
Is HF the strongest hydrogen bond?
The hydrogen bond in HF is strongest, because fluorine is the most electronegative element.
Which has higher boiling HBr or HF?
Answer and Explanation: HF has the highest boiling point among the given substances because of hydrogen bonding, a very strong dipole-dipole interaction. In the...
Why HI has higher boiling point than HCl and HBr?
HI has higher boiling point than HCl and HBr. 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.
What is the intermolecular forces of HF?
Quick answer: The major “IMF” in hydrogen fluoride (HF) is hydrogen bonding (as hydrogen is bonded to fluorine). Since the molecule is polar, dipole-dipole forces also exist along with London dispersion forces (Van der Waals' forces).
Question
Explain why hydrogen fluoride ( HF) has a higher boiling temperature than hydrogen chloride ( HCL ) ( 19.4 o o C vs. -85 o o C ), even though HF has a lower molecular weight.
Intermolecular bonding
Intermolecular bonding is the chemical property of a molecule to attach to another molecule. There are several types of chemical bonds like Covalent bonds, Ionic bonds, Hydrogen bonds, Metallic bonds, and Van der Waals interaction.
