Chapter 10, Problem 108E

Interpretation Introduction

Interpretation:

For each of the molecule that contains an expanded octet, Lewis structure is to be determined.

Concept Introduction: Expanded octets are an exception of Lewis structure where central atoms in a Lewis structure have more than eight electrons in their valence shells.

Lewis structure represents valence shell electrons, as dots are the symbol of the element. The Lewis structure of a molecule represents the sharing of two electrons in the chemical bond.

For molecules which obey the octet rule must have eight electrons in their valence shell. In the molecule, the total number of electron groups around the central atom is equal to the sum of lone pairs, a single bond, a double bond and triple bond around the central atom.
