Expert Answer

Step 1

The Lewis structure of any molecule represents the number of valence electrons between bonded atoms of the molecule. It indicates the number of bonds between all atoms. 

Step 2

The Lewis structure does not provide any information about the bond angle and shape. We can conclude the hybridization with the help of Lewis structure. The concept of hybridization and VSEPR theory must be used to explain the bond angle and shape of the molecule.

 

Step 3

To draw the Lewis structure we have to calculate the total number of v...
