Question

What is the effect of electron withdrawing group on the acidity carboxylic acid?

Open in App

Solution

An electron withdrawing group increases the acidity carboxylic acid. It disperses negative charge by inductive/ resonance effect and stabilizes the carboxylate ion. Thus, p-nitro benzoic acid (pKa 3.41) is more acidic than benzoic acid (pKa 4.19). Nitro group is electron withdrawing group.
