Chapter 8.6, Problem 1PPB

Interpretation Introduction

Interpretation:

The measured dipole moment of $\text{NaI}$ is to be determined.

Concept introduction:

Polarity of a bond can be determined by the dipole moment, which is the product of charge $\left(Q\right)$ and the distance between the charges $\left(r\right)$. It is given by:

$\mu =Q\times r$

Bond length of an ionic compound is the sum of the ionic radii of their respective ions.

Percent ionic character gives the percentage of ionic character present in any of the compounds. It is given by:

$\text{Percent ionic character}=\frac{\text{Measured dipole moment}\left({\mu }_m\right)}{\text{Calculated dipole moment}\left({\mu }_c\right)}\times 100$
