What are Dipole-Induced Dipole Forces

Answer: Dipole-induced dipole forces:

  • It refers to the process of generation of a dipole in an atom or a nonpolar molecule when a polar molecule disrupts the configuration of electrons in the nonpolar species. It can be depicted in the figures shown below,

Sodium (Na) has the atomic number 11 (Z=11). The electrical configuration of sodium is 2, 8, and 1 in written form. In the shells, K, L, and M, 2, 8, and 1 electron are dispersed. As a result, sodium’s valence electron is 1, and it must lose one electron from the outermost orbit to achieve an octet. Therefore, sodium has a valency of 1.

 

A spherical atom with no dipole.               The approach of a molecule with the dipole.

  • The dipole moment of the permanent dipole, as well as the polarisability of the electrically neutral molecule, influence the induced dipole moment.
  • This force’s interaction energy is proportional to the power of the distance between two molecules and inversely proportional to it.
  • The stronger the attractiveness, the higher the polarisability.
