Question

Why tropone and tropolone are more stable tahn anticipated?

Answer 1

In an extreme case the carbon atom has a full positive charge forming a tropylium ring which is an aromatic 6 electron system .Tropolone is acidic with a pKa of 7 which is in between that of phenol and benzoic acid . The increased acidity compared to phenol is due to regular resonance stabalization.
