General reaction scheme for the S N 1 reaction. The leaving group is denoted "X", and the nucleophile is denoted "Nu–H". The unimolecular nucleophilic substitution (S N 1) reaction is a substitution reaction in organic chemistry.
In chemistry, S N i (substitution nucleophilic internal) refers to a specific, regio-selective but not often encountered reaction mechanism for nucleophilic aliphatic substitution.
Sportsnet One (SN1 or SN One) is a Canadian English-language discretionary digital cable and satellite specialty channel owned by Rogers Sports & Media; it operates as a national sports channel complementing the Sportsnet group of regional sports networks. In addition to the national feed, the service operates a number of additional part-time ...
In coordination chemistry, the S N 1cB (conjugate base) mechanism describes the pathway by which many metal amine complexes undergo substitution, that is, ligand exchange. . Typically, the reaction entails reaction of a polyamino metal halide with aqueous base to give the corresponding polyamine metal hydroxi

The opposite pathway is dissociative substitution, being analogous to the Sn1 pathway. Examples of associative mechanisms are commonly found in the chemistry of 16e square planar metal complexes, e.g. Vaska's complex and tetrachloroplatinate. The rate law is governed by the Eigen–Wilkins Mechanism.
SN1 may refer to: SN1 reaction, a type of organic chemical reaction (7990) 1981 SN1, a Main Belt minor planet (7058) 1990 SN1, a main-belt minor planet;
The lowest rate of isomerization is at pH 4-5. Starting from either 1-lysoPC or 2-lysoPC, an equilibrium mixture of 90% 2-lysoPC and 10% 1-lysoPC is obtained with a half-time of about 10 minutes under physiological conditions [1] and about 1 hour under typical laboratory conditions. [2]
