Help please
Gases such as oxygen and nitrogen, O_2 and N_2, can be liquefied at low temperatures and high pressure as a result of _____. A) Ion-dipole forces B) Dipole-dipole forces C) Dipole-induced dipole forces D) Hydrogen-bonding E) London Dispersion forces What type of intermolecular forces exist between the molecules shown below: A) London-dispersion force B) Dipole-dipole force D) Ion-dipole force E) Ionic bonding Which of the following physical properties of a liquid depend on the magnitude (size) of its intermolecular force?
