Chapter 8, Problem 71P

(a)

Interpretation Introduction

Interpretation:

• The contribution of resonance structure to resonance hybrid of the given following has to be investigated.

Concept Introduction:

Resonance Contributor: The appropriate structure with the localized 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.
