Chapter 18, Problem 18.19P

Interpretation Introduction

(a)

Interpretation: All resonance structures for the carbocation of given compound formed by ortho attack of the electrophile ${}^{+}{\text{NO}}_{\text{2}}$ are to be drawn. The resonance structures are to be labeled as stable or unstable.

Concept introduction: Resonance structure is a blend of two or more Lewis structures. Resonance structures are represented by a double headed arrow between the structures.

Interpretation Introduction

(c)

Interpretation: All resonance structures for the carbocation of given compound formed by ortho attack of the electrophile ${}^{+}{\text{NO}}_{\text{2}}$ are to be drawn. The resonance structures are to be labeled as stable or unstable.

Concept introduction: Most of the organic structures cannot be represented using single Lewis structure. Therefore, there exists more than one Lewis structure for representing a molecule or ion. These structures are known as resonance structures.
