Chapter 7, Problem 43P

(a)

Interpretation Introduction

Interpretation:

Resonance contributor that provides the greater contribution to resonance structure to resonance hybrid has to be identified.

Concept Introduction:

Resonance Contributor: The appropriate structure with the delocalized electrons is called a resonance contributor, a resonance structure, or a contributing resonance structure.

Delocalized electrons: The sharing of electrons between two or more atoms known as delocalization of electrons.  In order to have delocalized electrons, the system must be planar and have alternative double bonds and single bonds.

Resonance hybrid: the actual structure with delocalized electrons is called a resonance hybrid.
