Does conjugation in aromatic molecule makes a the molecule more acidic or less acidic compared to its related non-aromatic compound?
As a example take the compounds below

As the acidity increases when the charge on the conjugate base can be delocalized over two or more atoms through resonance, so the aromatic molecule is more acidic?
