What is the effect of electrons with drawing group on the acidity of carboxylic acid |
|
Answer» 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. |
