Respuesta :
The intermolecular forces that exist between the molecules of a liquid are closely correlated with its vapor pressure. The rate of evaporation and vapor pressure decrease in direct proportion to the strength of these forces.
What impact do intermolecular forces have on physical attributes?
Two molecules are held together by intermolecular forces. Intermolecular forces have an impact on physical qualities. As intermolecular tensions increase, melting, boiling, and freezing points rise. As intermolecular forces grow, vapor pressure falls.
Why do stronger vapor pressures result from weaker intermolecular forces?
Lower intermolecular forces result in a higher vapor pressure because it is simpler to evaporate a compound at a higher vapor pressure.
How does intermolecular force depend on electronegativity?
Dipole-dipole interactions will be stronger the greater the difference in electronegativity. Therefore, compounds with a larger difference in electronegativity will have stronger intermolecular forces. Hydrogen dipole bonds have the potential to form highly strong bonds in specific situations.
