Paragraph The acidic strength of saturated aliphatic carboxylic acids depends mainly upon the inductive effect of the substitutent and its position w.rt, the -COOH group. Whereas electron donating substitutents tend to decrease, electron withdrawing substitutents tend to increase the acid strength. The acidic strength of aromatic carboxylic acids, on the other hand, depends upon both the inductive and the resonance effect of the substitutents.
