Definitions:

Nonaromatic

Refers to compounds that do not possess a ring structure with alternating single and double bonds, lacking the characteristic stability of aromatic systems.

Nonaromatic

Refers to organic compounds that do not exhibit the stability associated with aromatic rings, often lacking delocalized pi-electron systems.

[10]annulene

A ten carbon ring compound with alternating single and double bonds, known for its unusual properties and contribution to the study of aromaticity.

Aromatic

A class of cyclic, planar compounds with electrons delocalized over the entire structure, providing unique stability, examples include benzene.
