Chapter 6.6, Problem 6.6.3SR

Interpretation Introduction

Interpretation:

The number of electrons surrounding the central atom of ${\text{BBr}}_{\text{3}}$ has to be given.

Concept Introduction:

• Lewis structures are diagrams that represent the chemical bonding of covalently bonded molecules and coordination compounds.
• It is also known as Lewis dot structures which represents the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.
• The Lewis structure is based on the concept of the octet rule so that the electrons shared in each atom should have eight electrons in its outer shell.
• Atoms can be stable even though the number of valence electrons in the atoms in a molecule is less than eight and is called incomplete octet
• Atoms can be stable even though the number of valence electrons in the atoms in a molecule is more than eight and is called expanded octet
