Question

in ion dipole forces the magnitude of the interaction energy is​

Answer 1

Answer:

An ion dipole interaction is the intermolecular force of attraction between a cation or anion and a molecule.

For ion dipole interaction, the interaction is between a dipole moment$( u )$. If the two equal and opposite charges $q+$ and $q-$ are separated by distance $r$, then the dipole moment is given by

                                  $u = qr$  

And the potential energy of an ion - dipole interaction is given by

$E$ ∝ $\frac{|Z+-|u }{r^{2} }$

  where $Z+-$ is the charge on ion.

And $r$ is the distance between the ion and molecular dipole.

Answer 2

Explanation:

The ion-ion interaction energy is inversely proportional to the distance between the ions (1/r), while the ion-dipole energy is inversely proportional to the square (1/r2).
