| Apr 4, 2023 at 13:05 | comment | added | Ham Lemon | Ok, so i get what you are trying to say, but just another thing to be sure of, is it possible for a monocyclic planar molecule with 4n+2 π electrons to be non aromatic just because it does not have continuous conjugation (and rather has cross conjugation)? | |
| Apr 4, 2023 at 12:27 | comment | added | Ivan Neretin | Yes, that's pretty impressive for an organic acid that does not even have a -COOH group. | |
| Apr 4, 2023 at 10:55 | comment | added | Oscar Lanzi | The aromatic character of the carbonyl ring anions is one factor that makes the neutral compounds relatively strong acids. Croconic acid, in particular, has a second deprotonation constant approaching that of sulfuric acid, without the use of halogen or cyano functions. | |
