Deprotonation
Deprotonation is a chemical reaction that involves the removal of a proton (H+) from a molecule or ion. This process is a fundamental concept in chemistry, particularly in acid-base reactions and organic chemistry.
Pronunciation
Deprotonation: /dēˌprōtəˈnāSH(ə)n/
Etymology
The term "deprotonation" is derived from the prefix "de-", meaning "removal of", and "proton", referring to the hydrogen ion (H+) that is removed during the process.
Process
Deprotonation is the reverse process of protonation, where a proton is added to a molecule or ion. It is a common step in many chemical reactions, including acid-base reactions, where a base accepts a proton from an acid, resulting in the deprotonation of the acid and the protonation of the base.

- Base: A substance that can accept a proton in a chemical reaction.
- pKa: A measure of the strength of an acid in solution, which is directly related to its tendency to undergo deprotonation.
- Bronsted-Lowry Theory: A theory of acids and bases that defines an acid as a proton donor and a base as a proton acceptor.
