Chapter 8, Problem 8.35P

(a)

Interpretation Introduction

Interpretation:

The shape, bond angle and bond polar of ${\text{XeF}}_{\text{2}}$ has to be predicted.

Concept Introduction:

Polarity results from the uneven partial charge distribution between various atoms in a compound.  Atoms, such as nitrogen, oxygen, and halogens that are more electronegative have a tendency to have partial negative charges.  Atoms, such as carbon and hydrogen, have a tendency to be more neutral or have partial positive charges.

Polar nature of the molecules can be measured by the dipole moment.  If a molecule has zero dipole moment then it is a non polar molecule.  If a molecule has a net dipole moment then it is a polar molecule.

(b)

Interpretation Introduction
