Chapter 5, Problem 26CTQ

(a)

Interpretation Introduction

Interpretation: Categorization of resonance structures as “Equivalent” and “Not equivalent” resonance structure for the bases mentioned below should be determined.

  Organic Chemistry: A Guided Inquiry, Chapter 5, Problem 26CTQ , additional homework tip  1

Concept introduction: When one single structure is unable to describe all the properties of single molecule, a phenomenon called resonance comes into play. This arises when two or more than two Lewis structures are possible for one molecule. All such structures are called resonating structures and have same placement of atoms in them but these have different locations of bond pairs and lone pairs. The resonating structures are inter-convertible with each other. The resultant of all the resonating or contributing structures is called the resonance hybrid.

(b)

Interpretation Introduction

Interpretation: Resonance structure in base mentioned below that has lowest potential energy should be determined.
