bilancin
Bilancin is a hypothetical chemical compound used in theoretical chemistry and, occasionally, in science fiction, to illustrate issues of aromaticity, substitution, and molecular stability. The term bilancin is not associated with any established isolation or spectroscopic characterization in peer-reviewed journals; no confirmed natural occurrence is known.
The name is used in pedagogical contexts to model a two-ring polycyclic aromatic system. In common depictions,
In discussions, bilancin may be used to compare reaction pathways, such as cyclization and dehydrogenation steps,
The bilancin concept can appear in textbooks and online resources as a didactic tool rather than a
