Chapter 15, Problem 15.55E

Interpretation Introduction

(a)

Interpretation:

The aromatic cyclopolyenes with a single positive charge are to be predicted.

Concept introduction:

The movement of delocalized pi electrons leads to the corresponding resonance structures. The stability of a compound depends upon the number of resonating structures. The compounds which follow the Huckel rule of aromaticity are known as an aromatic compound.

Interpretation Introduction

(b)

Interpretation:

The aromatic cyclopolyenes with double positive charge are to be predicted.

Concept introduction:

The movement of delocalized pi electrons leads to the corresponding resonance structures. The stability of a compound depends upon the number of resonating structures. The compounds which follow the Huckel rule of aromaticity are known as aromatic compound.
