                          b.

Step-by-Step Solution

Answer

Answer

a. The resonance structure of the compound is given below:

                   

b. The resonance structures of the compound is given below

                     

Step-by-Step Solution Step 1: Resonance structures

The phenomenon of “electron delocalization” can be explained with the help of specific structures that are referred to as resonance structures.

Step 2: Resonance structures of compound a

a. The conversion of the first resonance structure to the second resonance structure can be given in the following manner:

                       

                                   Representation of resonance structure

 

The position of atoms is similar in both structures. However, the atoms have a different arrangement, and hence, one compound is obtained by delocalizing the electrons in the other compound

b. Representation of resonance structure

 

The position of atoms is similar in both structures. However, the atoms have a different arrangement, and hence, one compound is obtained by delocalizing the electrons in the other compound

                             

                               Representation of resonance structure

The position of atoms is the same in both the structures given above. However, the arrangement of electrons is different. Hence, these compounds are resonance structures of each other.
