Answer

a.

b.

Step by step solution

01

Step-by-Step Solution Step 1: Resonance structures

The compounds which can be constructed in Lewis structures and depict electron bonds are named resonating structures. The formal charges and respective bonds are presented.

02

Curved arrow mechanism

The head and tail part of the arrow represents the origin and transfer of electrons. This arrow mechanism helps to identify the movement of electrons and the bonds involved in formation and breakdown.

03

 Step 3: Determination of second resonance structure

a, When electrons move, a positive and negative charge is produced in carbon and oxygen atoms, respectively.


The second resonance structure of a

b, When the negative charge on carbon shifts on the carbon-carbon bond, a double bond forms. Further, electrons of double bond shift, and a single bond replace the double bond in the structure formed.

The second resonance structure of b
