Acidity of aromatic acids and effect of substituent on acidity
Aromatic carboxylic acids, such as benzoic acid, are stronger acids compared to aliphatic carboxylic acids like acetic acid. This is because benzoic acid has a pKa value of 4.2, which is slightly lower than that of acetic acid (pKa= 4.8). The carboxylic group in benzoic acid is attached to an sp2 hybridized carbon atom, which … Read more
