Greater the inter-molecular forces, greater the boiling point. HF has strong inter-molecular forces, due to hydrogen bonding between HF and H.
Why HF has a higher boiling point?
– The other halogens are not as electronegative and so other hydrogen halides cannot form hydrogen bonds between molecules. Only London Forces are formed. – Therefore more energy is required to break the intermolecular forces in HF than the other hydrogen halides and so it has a higher boiling point.
Why does HF have a higher boiling point than F2?
HF has a higher boiling point than F2 because more effort is needed to make H and F atoms stop being close to each other (electrostatic attraction causes close proximity).
Why is boiling point of HCl highest while that of HCl lowest?
HCL has the higher boiling point because it exhibits stronger dipole-dipole forces between molecules. …
Why is the boiling point of HCl less than that 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.
Does HCl have a high melting point?
Hydrogen chloride (HCl) has a melting point of -114.2 °C. Sodium chloride (NaCl) has a melting point of 801 °C.
Why does HF have hydrogen bonding but not HCl?
The atom of chlorine is too heavy. The size of the atom, considering its electronegativity, is such that its electron density is too low for hydrogen bonds to form. This is why, while HF does, HCl does not demonstrate hydrogen bonding. Was this answer helpful?
