Deprotonation is a fundamental chemical reaction where a proton (H+) is removed from a molecule or ion. This process typically involves a base, which accepts the proton. Acids, by definition, are proton donors, and their reaction with a base is a deprotonation. The molecule that loses the proton becomes a conjugate base, and the base that accepts the proton becomes a conjugate acid. For instance, when water acts as an acid, it deprotonates to form a hydroxide ion (OH-) and a hydronium ion (H3O+) when it reacts with itself. Similarly, in an acid-base reaction, a strong acid will readily deprotonate a weaker base.

The strength of an acid is directly related to its ability to deprotonate a given molecule. More acidic compounds have a greater tendency to donate a proton. Factors like electronegativity of the atom bearing the acidic hydrogen, resonance stabilization of the conjugate base, and the inductive effect can influence the acidity and thus the ease of deprotonation. Deprotonation is a crucial step in many chemical processes, including organic synthesis, acid-base catalysis, and biological reactions. Understanding deprotonation is essential for predicting reaction outcomes and designing chemical transformations. It is the reverse of protonation, where a proton is added to a molecule or ion.
