Chapter 16.9D, Problem 16.19P

(a)

Interpretation Introduction

Interpretation:

If the given compound is aromatic, antiaromatic or non-aromatic is to be identified.

Concept introduction:

Aromatic compounds are defined as those compounds that have cyclic and planar structure. The pi network of aromatic compounds must satisfy Huckel’s rule $\left(4n+2\text{π}\right)$ electrons.

Antiaromatic compounds are cyclic, planar and completely conjugated with $4n\text{π}$ electrons. Non-aromatic compounds are those that lack one or more of the requirements to be aromatic.
