Based on this discussion, we analyze the case of cyclo [18]carbon, a molecule that was characterized for the first time in 2019 in a scanning tunneling microscope. From the very beginning, this molecule was classified as an aromatic molecule. In the present work, we challenge this classification and provide arguments to classify this molecule as a non-aromatic speciesFunding source: Departament d'Innovació, Universitats i Empresa, Generalitat de Catalunya: grant number: 2021SGR623; ICREA Academia prize 2024 to M.S.; Infrastruktura PL-Grid: grant number: PLG/2024/017801; Ministerio de Ciencia, Innovación y Universidades: grant number: PID2023-147424NB-I00 and Narodowe Centrum Nauki: grant number: 2021/42/E/ST4/00332
