Chapter 8, Problem 11PP

Interpretation Introduction

Interpretation:

Whether the given molecules are polar or nonpolar is to be predicted.

Concept Introduction:

The number of bonded atom and unshared electron pairs determines the parent structure of molecules or ions.

Parent structures help predict the shape of molecules.

In a polar covalent bond, a pair of electrons are shared unequally between two bonded atoms. This leads to the formation of partial charges.

Using the value of electronegativity, it can be decided if a molecule is polar or not.

If the electronegativity values of the bonded atoms are different then the bond is polar.
