Chapter 10, Problem 41E

Interpretation Introduction

Interpretation:

Polarity of the bond in each diatomic molecule should be shown and partial charges on the atoms in each molecule should be calculated.

Concept introduction:

When use a cross-bar arrow, it points to the more electronegative atom.

The partial charge can be calculated as follows:

$\text{Partial charge (}\delta \text{) = }\frac{\text{Dipole moment (}\mu \text{)}}{\text{Bond length (d)}}$

As the decimal fraction of the elementary charge, the partial charge can be calculated as:

$\text{Partial charge as the decimal fraction of the elementary charge = }\frac{\text{Partial charge }}{\text{Charge of an electron }}$

Also,

$1\text{ Debye = 3}\text{.34 }\times {\text{10}}^{-30}\text{ C m}$
