WebTrifluoroacetic acid ( TFA) is an organofluorine compound with the chemical formula CF 3 CO 2 H. It is a structural analogue of acetic acid with all three of the acetyl group's hydrogen atoms replaced by fluorine atoms and is a colorless liquid with a vinegar -like odor. Trifluoroacetic acid in a beaker. WebSulfonic acids are similar to carboxylic acids and have the general structure of RSO 3 H. Sulfonic acids are very strong acids (pKa ~ -7). The most common sulfonic acid is p-toluenesulfonic acid. The conjugate bases of sulfonic acids are called sulfonate anions and are resonance stabilized. Consequently, sulfonate anions make good leaving groups.
