Problem: Write the resonance forms of ozone, O 3, the component of the upper atmosphere that protects the Earth from ultraviolet radiation.

FREE Expert Solution

We are being asked to identify the resonance forms of ozone (O3)

We will have to draw the Lewis Structure of O3 first.


Step 1: Determine the central atom in this molecule.

  •  3 O atoms are the central atoms 


Step 2: Calculate the total number of valence electrons present.          

O3:

             Group              Valence Electrons

O          6A                    6 valence e x 3

                 Total = 18 valence e-


Step 3: Draw the Lewis Structure for the molecule

•  O → prefers to have a complete octet (8 e- around them)
