Chapter 10, Problem 10A.5E

(a)

Interpretation Introduction

Interpretation:

The units of polarizability, $\text{α}$ has to be given.

Concept introduction:

Polar covalent bond involves an unequal sharing of electrons between two bonded atoms; it creates a partial separation of charge and a dipole moment.

Covalent bonds are polar, if there is a difference in electronegativity between the bonded atoms.

Direction of dipole moment in a molecule is can be represented as follows,

  $\text{Positive }\underset{}{\to }\text{ Negative}$

(b)

Interpretation Introduction

Interpretation:

The units of polarizability volume can be expressed in ${\text{m}}^{\text{3}}$ has to be proven.

Concept introduction:

Polar covalent bond involves an unequal sharing of electrons between two bonded atoms; it creates a partial separation of charge and a dipole moment.

Covalent bonds are polar, if there is a difference in electronegativity between the bonded atoms.

Direction of dipole moment in a molecule is can be represented as follows,

  $\text{Positive }\underset{}{\to }\text{ Negative}$

Calculation of the polarizability volume:

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