Interpretation Introduction

Interpretation:

The resonance structure of the given molecule is to be determined

Concept Introduction:

When the electron distribution of a molecule can be depicted correctly in more than one way using different Lewis structures, the drawings are called resonance structures.

Resonance structures have no discrete existence of their own but, taken in combination, describe the true structure of the molecule.
