Chapter 6, Problem 6.2KSP

Interpretation Introduction

Interpretation:

The species that has odd number of electrons should be identified from the given options.

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 8 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 8 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 8 and is called expanded octet.
• In some cases the atom in a molecule are surrounded by odd number of electrons and is an exception for octet rule.  These type of molecule are known as free radicals and they are highly reactive.

To determine: central atom of species that does not obey octet rule.is
