Chapter 10, Problem 108E

Interpretation Introduction

Interpretation: The Lewis structures for each molecule is to be written.

Concept Introduction: Expanded octets are those whose central atoms in a Lewis structure have more than eight electrons in their valence shells and it is one of the exceptions to octet rule.

Lewis structure also known as lewis dot structures represents the molecules by the electron dot model. The Lewis structure represents the sharing of two electrons in the chemical bond.

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