SN2 reaction is a type of nucleophilic substitution in organic chemistry, where a nucleophile attacks the backside of a leaving group on a carbon atom. Learn about the reaction mechanism, the factors that affect the rate of the reaction, and some examples of SN2 reactions.
SN1 reaction is a unimolecular nucleophilic substitution in organic chemistry involving a carbocation intermediate. Learn the mechanism, rate law and examples of SN1 reaction, and how to distinguish it from SN2 reaction.
Learn about the general reaction, mechanisms and factors affecting the rate of nucleophilic substitution, a class of chemical reactions in which an electron-rich species replaces a functional group on an electron-deficient molecule. Compare the S N 1 and S N 2 mechanisms and see examples of common reactions involving this type of mechanism.
Learn about the mechanism, activation, and examples of nucleophilic aromatic substitution (SNAr), a reaction in which a nucleophile displaces a leaving group on an aromatic ring. Find out how electron-withdrawing groups, leaving groups, and nucleophiles affect the reaction rate and selectivity.
SNi (substitution nucleophilic internal) is a reaction mechanism for nucleophilic aliphatic substitution with retention of configuration. Learn about its features, examples, and related reactions such as SN1 and SN2.
Hammond's postulate is a hypothesis in physical organic chemistry that describes the geometric structure of the transition state in a reaction. It states that the structure of the transition state resembles that of the species nearest to it in free energy, which can be used to explain and rationalize the Bell–Evans–Polanyi principle and reaction coordinate diagrams.
The Hammett equation is a linear free-energy relationship for reactions involving benzoic acid derivatives with meta- and para-substituents. It relates reaction rates and equilibrium constants to substituent constants and reaction constants, and can be used to analyze the effects of substituents on acidity, basicity, and reactivity.
The Finkelstein reaction is a type of S N 2 reaction that involves the exchange of one halogen atom for another in alkyl halides. It is an equilibrium reaction that can be driven to completion by using differential solubility or excess of the desired halide, and it can be used as a qualitative test for alkyl halide classes.
