Antiaromaticity — Antiaromatic molecules are cyclic systems containing alternating single and double bonds, where the pi electron energy of antiaromatic compounds is higher than that of its open chain counterpart. Therefore antiaromatic compounds are unstable and… … Wikipedia
Aromaticity — is a chemical property in which a conjugated ring of unsaturated bonds, lone pairs, or empty orbitals exhibit a stabilization stronger than would be expected by the stabilization of conjugation alone. It can also be considered a manifestation of… … Wikipedia

Homoaromaticity — in organic chemistry is found in conjugated cyclic systems that are able to skip a part of the ring as opposed to regular aromaticity. Like ordinary aromatic compounds, homoaromatic compounds are more stable than what would be expected based on… … Wikipedia
Anti-aromaticité — Un composé anti aromatique est un composé cyclique contenant une alternance de liaisons doubles et simples, où l énergie des électrons pi du composé anti aromatique est supérieure à celle du composé équivalent en chaine ouverte. Ainsi, les… … Wikipédia en Français
