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, a nucleophilic substitution (S N) is a class of chemical reactions in which an electron-rich chemical species (known as a nucleophile) replaces a functional group within another electron-deficient molecule (known as the electrophile).
S N i reaction mechanism Sn1 occurs in tertiary carbon while Sn2 occurs in primary carbon. See also. Nucleophilic acyl substitution; References. This page was last ...
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.

The opposite pathway is dissociative substitution, being analogous to the Sn1 pathway. Intermediate pathways exist between the pure associative and pure dissociative pathways, these are called interchange mechanisms. [1] [2]
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
