(a)
Interpretation:
The Lewis structure for
Concept Introduction:
Lewis structure is also known as Lewis dot diagrams or electron dot structures. The bond between atoms and lone pairs of electrons that is present in the molecule. Lewis structure represents each atom and their position in structure using the chemical symbol. Excess electrons forms the lone pair are given by pair of dots, and are located next to the atom.
Octet rule says that the tendency of atoms to get eight electrons. Octet can be made by sharing of electrons from the neighbor atom to get stable configuration.
