Question
Chapter 2, Problem 27EQ
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.

Some of the figures represent invalid sets of resonance structures for this molecule.
Select all the VALID sets of resonance structures.
Draw the Lewis structures for the following four molecules, being sure to show all steps following the methods covered in class. Structures without work shown will be marked incorrect. Also, one of these molecules has resonance structures – for this compound, make sure to include all resonance structures, indicate formal charges for each atom.
