Definitions:

Cyclobutadiene

A highly unstable, conjugated diene with the molecular formula C4H4, characterized by a square planar structure that challenges classical bonding theories.

[4]annulene

A cyclic compound made up of four conjugated carbon atoms, known for its planar structure and aromatic behavior despite having 4 π-electrons, which does not follow Huckel's rule for aromatic stability.

Aromatic

Relates to organic compounds containing one or more planar ring structures with delocalized π-electrons, exhibiting unique stability and reactions.

Nonaromatic

Referring to organic compounds that do not meet the criteria for aromaticity, often being less stable and more reactive.
