Chapter 17, Problem 17.51P
Interpretation Introduction

(a)

Interpretation: The MOs of cyclooctatetraene as bonding, antibonding, or nonbonding are to be labeled.

Concept introduction: The inscribed polygon method is helpful to predict whether a compound involves completely filled bonding MOs or not. The all bonding MOs, and the HOMOs of an aromatic compound are completely filled. However, the antibonding MOs are completely vacant.

Interpretation Introduction

(b)

Interpretation: The arrangement of electrons in the MOs of cyclooctatetraene is to be stated and an explanation for the not aromatic nature of it is to be stated.

Concept introduction: The inscribed polygon method is helpful to predict whether a compound involves completely filled bonding MOs or not. The all bonding MOs, and the HOMOs of an aromatic compound are completely filled. However, the antibonding MOs are completely vacant.

Interpretation Introduction

(c)

Interpretation: The number of π electrons that dianion of cyclooctatetraene contain is to be predicted.

Concept introduction: The inscribed polygon method is helpful to predict whether a compound involves completely filled bonding MOs or not. The all bonding MOs, and the HOMOs of an aromatic compound are completely filled. However, the antibonding MOs are completely vacant.

Interpretation Introduction

(d)

Interpretation: The arrangement of π electrons of dianion in MOs is to be stated.

Concept introduction: The inscribed polygon method is helpful to predict whether a compound involves completely filled bonding MOs or not. The all bonding MOs, and the HOMOs of an aromatic compound are completely filled. However, the antibonding MOs are completely vacant.

Interpretation Introduction

(e)

Interpretation: The classification of dianion as aromatic, nonaromatic, or antiaromatic is to be stated and its being so is to be explained.

Concept introduction: The inscribed polygon method is helpful to predict whether a compound involves completely filled bonding MOs or not. The bonding MOs, and the (HOMOs) of an aromatic compound are completely filled. However, the antibonding MOs are completely vacant.
