Deprotonation is a chemistry term that refers to the removal of a proton (hydrogen cation H⁺) from a molecule, forming the conjugate base. Chemistry (from Egyptian kēme (chem meaning "earth") is the Science concerned with the composition structure and properties The proton ( Greek πρῶτον / proton "first" is a Subatomic particle with an Electric charge of one positive Hydrogen (ˈhaɪdrədʒən is the Chemical element with Atomic number 1 An ion is an Atom or Molecule which has lost or gained one or more Valence electrons giving it a positive or negative electrical charge In Chemistry, a molecule is defined as a sufficiently stable electrically neutral group of at least two Atoms in a definite arrangement held together by Within the Brønsted - Lowry ( protonic) theory of acids and bases, a conjugate acid is the acid member HX of a pair of two compounds that transform The relative ability for a molecule to give up a proton is measured by a pK_a value. A low pK_a value indicates that the compound is acidic and will easily give up its proton to a base. In Chemistry, a base is most commonly thought of as an aqueous substance that can accept Protons This refers to the Brønsted-Lowry theory of acids and The pK_a of a compound is determined by many things, but most significantly it is impacted by the stability of the conjugate base, that is maily determined by the ability (or inability) of the conjugated base to stabilize the negative charge. The negative charge is stabilized when it is distributed on a large surface or a long chain. One of the mechanisms that distributs the negative charge on a longer chain or a ring is resonance. Resonance in Chemistry is a theory used to represent and model certain types of non-classical Molecular structures Resonance is a key component Solvent also could assist in the stabilization of the negative charge on a conjugated base.

Bases used to deprotonate depend on the pK_a of the compound. Where the proton is not particularly acidic, and as such, the molecule does not give up its proton easily, a base stronger than the commonly known hydroxides are required. In Computer science, ACID ( Atomicity Consistency Isolation Durability) is a set of properties that guarantee that Database transactions are In Chemistry, hydroxide is the most common name for the diatomic Anion OH− consisting of Oxygen and Hydrogen Hydrides are one of the many types of powerful deprotonating agents. Hydride is the name given to the negative Ion of Hydrogen, H− Common hydrides used are sodium hydride and potassium hydride. Sodium hydride is the Chemical compound with the formula NaH It is primarily used as a strong base in Organic synthesis. Potassium hydride, KH is a Chemical compound of Potassium and Hydrogen. These bases are so powerful because the hydride forms hydrogen gas when the proton from the other molecule is removed. Hydrogen (ˈhaɪdrədʒən is the Chemical element with Atomic number 1 This page is about the physical properties of gas as a state of matter However, the production of hydrogen also means that deprotonation using agents that release hydrogen are dangerous and should be done in an inert atmosphere (e. In English to be inert is to be in a state of doing little or nothing An atmosphere (from Greek ατμός - atmos, " Vapor " + σφαίρα - sphaira, " Sphere " g. nitrogen) as water is a source of protons that is present in the air around us all the time and may react with the hydride instead of the desired molecule or may set on fire. Nitrogen (ˈnaɪtɹəʤɪn is a Chemical element that has the symbol N and Atomic number 7 and Atomic weight 14
