Add curved arrows to both structures to show the delocalization of electron pairs needed to form the other resonance contributor.
Homework Answers
This problem is based on the concept of resonance.
Two resonating structures are given. Curved arrows are shown in one of the structures and we have to add the curved arrows on other structure to show the delocalization of electron pairs needed to form the other resonance contributor.
When a single Lewis structure is not able to explain the bonding of a compound, it gives rise to certain phenomenon called resonance. Various resonating structures of a single compound arise due to the delocalization of electrons (lone pairs and electrons). All the resonating structures give rise to a resonance hybrid structure which has minimum energy and explains the stability and bonding of the molecule.
The structure of the first resonating form is given below:
The curved arrow representation is given below:
The curved arrow represenation of both resonating forms is given below:
The curved arrow represenation of the interconversion of two resonating forms is given below:
