Interpretation Introduction

Interpretation:

The order of increasing percent ionic character should be identified from the given options.

Concept Introduction:

• Percent ionic character is used get an idea about the type of bond. It is the percentage of ratio of observed dipole moment and calculated dipole moment.

$\text{The percent ionic character}\text{=}\frac{\text{μ}\left(\text{observed}\right)}{\text{μ}\left(\text{calculated}\text{assuming}\text{discrete}\text{charges}\right)}\text{×100}\text{\%}$

• Dipole moment $\left(\text{μ}\right)$ occurs on polar bonds where there is a separation of charges within the molecule. Dipole moment is formed due to the difference in electronegativity of atoms within the molecule and is a measure of polarity.

$\text{μ=}\text{Q}\text{×}\text{r}$

Where,

$\begin{array}{c}\text{μ}\text{=}\text{Dipole moment}\\ \text{Q}\text{= partial charges}\\ \text{r}\text{= distance between partial charges}\end{array}$

To determine: Order of increasing percent ionic character
