The strongest attractive forces between molecules of O_2 are: ionic covalent hydrogen bonding dipole-dipole attractions dispersion forces Solution The attractive forces between molecules of O2 will be dispersion forces. This is because O2 is a non-polar molecule so there will be no dipole-dipole interactions, also there is no hydrogen atom so no question of Hydrogen bonding. Dispersion forces are exhibited by non-polar molecules because of thecorrelated movements of the electrons in interacting molecules. The electrons in adjacent molecules repel each other and so they run away from their usual place. As a result, electron density in a molecule becomes redistributed in proximity to another molecule, which is according to quantum mechanical theory of dispersion forces. This is frequently described as the formation of instantaneous dipoles that attract each other. These type of Dispersion forces are present between all chemical groups, and usually represent the main part of the total interaction force in condensed matter..

Solution
The attractive forces between molecules of O2 will be dispersion forces. This is because O2 is a
non-polar molecule so there will be no dipole-dipole interactions, also there is no hydrogen atom
so no question of Hydrogen bonding. Dispersion forces are exhibited by non-polar molecules
because of thecorrelated movements of the electrons in interacting molecules. The electrons in
adjacent molecules repel each other and so they run away from their usual place. As a result,
electron density in a molecule becomes redistributed in proximity to another molecule, which is
according to quantum mechanical theory of dispersion forces. This is frequently described as the
formation of instantaneous dipoles that attract each other. These type of Dispersion forces are
present between all chemical groups, and usually represent the main part of the total interaction
force in condensed matter.
