Hückel i Möbius - zjawisko aromatyczności dawniej i dziś
PublikacjaPojęcie aromatyczności zagościło w chemii, kiedy to August W. Hofmann użył go do opisu pewnej grupy kwasów karboksylowych. W 1856 ukazał się jego artykuł "On insolinic acid", gdzie opisywał on utlenianie kwasu kuminowego kwasem chromowym. Stwierdzenie "kwasy aromatyczne" pojawia się tam dwukrotnie, jednak bez żadnego wyjaśnienia. Z czasem wszystkie związki o wysokim stopniu nienasycenia oraz nadzwyczajnej trwałości (czyt. pochodne...
