Pronated chemistry
WebProtonation of the alcohol converts a poor leaving group (OH-) to a good leaving group (\)H_2O\_), which makes the dissociation step of the SN1 mechanism more favorable. In … WebDeprotonation (or dehydronation) is the removal (transfer) of a proton (or hydron, or hydrogen cation), (H +) from a Brønsted–Lowry acid in an acid–base reaction. [1] [2] The species formed is the conjugate base of that acid. The complementary process, when a proton is added (transferred) to a Brønsted–Lowry base, is protonation (or hydronation).

Hydrolysis of nitriles. A nitrile contains a triply bonded C = N group, which is another common type of polar bond. However, the carbon in a nitrile is at an oxidation state of +3, higher than the +2 for ketones or +1 for aldehydes. For this reason, nitriles are not carbonyl equivalents like imines; rather, they are at the same oxidation ...
