Concept explainers
(a)
Interpretation: The Lewis structure for the given molecule should be identified.
Concept Introduction:
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.
Sometimes the
Lewis structure for any molecule is drawn by using the following steps,
First the skeletal structure for the given molecule is drawn then the total number of valence electrons for all atoms present in the molecule is determined
The next step is to subtract the electrons present in the total number of bonds present in the skeletal structure of the molecule with the total valence electrons such that considering each bond contains two electrons with it.
Finally, the electrons which got after subtractions have to be equally distributed such that each atom contains eight electrons in its valence shell.
(b)
Interpretation: The Lewis structure for the given molecule should be identified.
Concept Introduction:
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.
Sometimes the chemical bonding of a molecule cannot be represented using a single Lewis structure.
