2 Cl 2 interaction that now follows is an example of a proper London dispersion interaction.
2.
*Well it says this-" Principal intermolecular interactions between alkane molecules are London dispersion interactions.
3.
The induction and dispersion interactions are always attractive, irrespective of orientation, but the electrostatic interaction changes sign upon rotation of the molecules.
4.
In this manner, the following approximation is obtained for the dispersion interaction E _ { AB } ^ { \ rm disp } between two atoms A and B.
5.
The first term in the next equation is Coulomb's law for a pair of ions, the second term is the short-range repulsion explained by Pauli's exclusion principle and the final term is the dispersion interaction term.
6.
However, no molecule is an ideal point dipole, and in the case of the HCl dimer, for instance, dipole-quadrupole, quadrupole-quadrupole, etc . interactions are by no means negligible ( and neither are induction or dispersion interactions ) .-->
