Chapter 10, Problem 10.40SP

Interpretation Introduction

Interpretation:

The percent ionic character of $\text{BrCl}$ bond has to be calculated.

Concept Introduction:

Dipole moment:

Dipole moment is quantity that is used to measure net molecular polarity. It is represented as $\text{μ,}$ and can be defined as magnitude of charge Q present at either end of specific dipole times the distance r seen between the charges. The dipole moment is expressed using formula,

$\text{μ}\text{=}\text{Q}\text{×}\text{r}$

Debye is the unit of dipole moment.

One Debye is equal to $\text{3}{\text{.336×10}}^{\text{-30}}\text{coulomb}\text{meters}\left(\text{c}\text{.m}\right)$ in S.I units.

Percentage ionic character:

The percentage ionic character is calculated by dividing observed dipole moment and calculated dipole moment.

$\text{\%}\text{ionic}\text{character =}\frac{\text{Observed}\text{dipole}\text{moment}}{\text{Calculated}\text{dipole}\text{moment}}$
