Chapter 10, Problem 10A.5ST

Interpretation Introduction

Interpretation:

The magnitude of the dipole moment of the molecule in addition to the permanent dipole moment has to be determined with given data.

Concept introduction:

Polar molecules are the molecules having a positive and negative end and so there will be a charge separation.

A polar molecule is a molecule where the polar bonds are asymmetrically arranged (the dipoles do not cancel)

A nonpolar molecule is a molecule with no polar bonds or a molecule where the polar bonds are symmetrically arranged.

In polar molecule the charge separation occurred with respect to the difference in electronegativity of atoms in the molecule.

Calculation of the polarizability volume:

  $\begin{array}{l}{\text{α}}^{\text{'}}\text{=}\frac{\text{α}}{{\text{4πε}}_{\text{0}}}\\ \\ {\text{α}}^{\text{'}}\text{-Polarizability}\text{volume}\\ \text{α-Polarizability}\\ {\text{ε}}_{\text{0}}\text{-8}{\text{.854×10}}^{\text{-12}}{\text{J}}^{\text{-1}}{\text{C}}^{\text{2}}{\text{m}}^{\text{-1}}\\ \end{array}$

Calculation of electric field:

  $\begin{array}{l}\text{E}\text{=}\frac{{\text{μ}}^{\text{*}}}{\text{α}}\\ \\ \text{E-Electric}\text{Field}\\ \text{α-Polarizability}\\ {\text{μ}}^{\text{*}}\text{-Electric dipole moment}\\ \end{array}$
