The strength of a carboxylic acid depends on the extent of its ionization constant: the more ionized it is, the stronger it is. As an acid becomes stronger, the numerical value of its pKa drops. In acids, the electron-releasing inductive effect of the alkyl group increases the electron density on oxygen and thus hinders the breaking of the O-H bond, which consequently reduces the ionization. Due to its greater ionization, formic acid (pKa=3.74) is stronger than acetic acid (pKa=4… WebJul 18, 2024 · They are derivatives of alcohols and are represented by the symbol (ROR’).
