Chapter 8.5, Problem 2RC

Interpretation Introduction

Interpretation: It should be determined for the number of lone pair of electron are present on the central atom $\left[\text{Xe}\right]$ in ${\text{XeF}}_{\text{2}}$.

Concept Introduction:

Resonance structures:

A molecule or ion which show more than structure but none of them are accurately correct show the known property of that molecule, and can lie between the canonical structure is known as resonance or canonical or contributing structure.

Polarity is the separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multiple moments.

Polar molecule must contain polar bond due to presence of electronegativity dereference between the bonded atoms.
