Chapter 8, Problem 131AP

Interpretation Introduction

Interpretation:

The electronegativity of O, F, and Cl by Mulliken and Pauling scale is to be determined. The electronegativities of the given elements on Mulliken and Pauling scale is to be compared.

Concept introduction:

Electronegativity is the measure of the ability of an atom to draw a pair of electrons towards itself.

According to Mulliken, it is given by:

$\text{EN}=\frac{{\text{IE}}_1+\text{EA}}{2}$

Here, ${\text{IE}}_1$ is the first ionization energy and $\text{EA}$ is the electron affinity.

Mulliken scale is converted to Pauling scale by dividing the Mulliken scale by $230\text{ kJ}/\text{mol}$
