WebTrifluoroacetic acid is a corrosive organofluorine compound that is structurally analogous to, but stronger than, acetic acid. Available in various quantities and reagent grades, it is used in NMR spectroscopy, mass spectrometry, organic synthesis, etc. Almost 100,000-fold more acidic than acetic acid, TFA is widely used in organic chemistry. WebAug 14, 2024 · The strongest acids are at the bottom left, and the strongest bases are at the top right. The conjugate base of a strong acid is a very weak base, and, conversely, the conjugate acid of a strong base is a very weak acid. Strong acids are H3O plus, HNO3, H2SO4, HCl, and HBr. Negligible acids are HS minus and OH minus.

WebFeb 19, 2024 · In general, the more stabilized the negative charge of the conjugate base is, the more the equilibrium favors that form, thus the more the acid dissociates, thus the "stronger" the acid is. So for a stronger acid (lower p K X a ), the negative charge must be more stabilized. When comparing C F X 3 C O O H (TFA) to C H X 3 C O O H (we'll use ...
