Why the boiling point of HBr is higher than HCl?
Explanation: HBr is a larger, more polarizable molecule than HCl . There should be a greater degree of dispersion forces, forces between molecules, operating in the HBr molecule, and thus the higher boiling point is observed.
Which has the highest boiling point HF HCl or HBr?
We can conclude, the order of boiling point followed is HF > HI > HBr > HCl. 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 the boiling point of HF is higher than 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. d) The atomic number for CL is greater than for F, so HF will have a higher boiling temperature.
Why does CL have a higher boiling point than HCl?
-Cl2 has stronger London-dispersion forces than liquid HCl. -Cl2 has the higher boiling point because liquid Cl2 has stronger dipole-dipole forces than liquid HCl. -HCl has the higher boiling point because liquid HCl has hydrogen-bonding interactions while liquid Cl2 has no hydrogen bonding interactions.
Why is the boiling point of HBr less then the boiling point of br2?
(c) Very polar – Hydrogen bonds between the molecules. HCl is more polar, but the increased mass of HBr gives it a higher boiling point. Br2 (58.78 °C) and I2 (184.35 °C) Answer. Both are nonpolar, but I2 has more mass and it is more polarizable (stronger intermolecular forces), so it will have the higher boiling point …
Why does ICl have a higher boiling point than Cl2?
ICl is polar and thus also exhibits dipole-dipole attractions; Br2 is nonpolar and does not. The relatively stronger dipole-dipole attractions require more energy to overcome, so ICl will have the higher boiling point.
Why does Cl2 have a higher boiling point than O2?
Liquid oxygen and liquid chlorine are both non-polar substances that experience only London dispersion forces of attraction. These forces are greater for Cl2 because it has more electrons, so Cl2 has a higher boiling point than O2.
