Chapter 16.8C, Problem 16.15P
Interpretation Introduction

Interpretation:

The explanations of the stability of the compounds, cyclopropenone and cycloheptatrienone and the instability of the compound cyclopentadienone are to be stated.

Concept introduction:

Huckel’s rule of the organic chemistry states that a monocyclic system will be aromatic only if there are (4n+2) pi electrons in the structure. The number of carbon atoms in the cyclic system is irrelevant to the aromaticity of the molecule.

It is based on the number of delocalised electrons present.
