Chapter 5, Problem 3SC

Interpretation Introduction

Interpretation:

A Lewis structure for a molecule in which the central atom lacks an octet is to be explained.

Concept introduction:

In Lewis structures, dots are used to represent the valence electrons.

Structures with octets (eight dots) or duets (two dots) are stable configurations.

The atoms in a molecule are linked together with each other through chemical bonds formed by the transfer or sharing of valence electrons of the atoms. The atoms tend to attain octet in order to gain stability.

Atoms can share more than one electron pair to form a complete octet resulting in multiple bonds.
