The given compound thatis not aromatic is to be determined.

Concept introduction:

Aromatic compounds are substancesthat contain alternating single and double bond in their chemical structure. All atoms must participate in resonance.

According to Huckel' rule, a compound is aromatic if it satisfies Huckel' rule, that is, $\left(\text{4n}+\text{2}\right)$ rule, where $\text{n}$ is the number of pi electrons.

An aromatic compound is more stable than an anti-aromatic compound.
