WebDispersion forces result from the formation of temporary dipoles, as illustrated here for two nonpolar diatomic molecules. Dispersion forces that develop between atoms in different molecules can attract the two molecules to each other. The forces are relatively weak, however, and become significant only when the molecules are very close. WebIn the presence of other molecules, these spontaneous dipoles have a propagating effect. If molecule A develops a spontaneous dipole, then the electron density in neighboring molecule B will by respond by developing a spontaneous (but opposite) dipole. The $\delta^+$ region of B will be close to the $\delta^-$ region of A.

WebTemporary dipoles form more readily in xenon, and dipoles are more easily induced in neighbouring xenon atoms. The van der Waals’ forces between xenon atoms are stronger than those between helium atoms. You can see a similar trend in the boiling points of the Group 7 elements. WebHow does a permanent dipole form? The permanent dipole in water is caused by oxygen’s tendency to draw electrons to itself (i.e. oxygen is more electronegative than hydrogen). The 10 electrons of a water molecule are found more regularly near the oxygen atom’s nucleus, which contains 8 protons. As a result, oxygen has a slight negative charge (-). raytheon application under reviewWebTemporary dipoles are created when electrons, which are in constant movement around the nucleus, spontaneously come into close proximity.
