7.1: Nucleophilic Substitution Reaction Overview
2021年12月16日 · Learn the key terms and concepts of nucleophilic substitution reaction, such as electrophile, nucleophile and leaving group. Understand the kinetics and mechanisms of SN2 and SN1 reactions with examples and diagrams.
Nucleophilic substitution - Wikipedia
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).
Nucleophilic Substitution (SN1, SN2) - Organic Chemistry Portal
Nucleophilic substitution is the reaction of an electron pair donor (the nucleophile, Nu) with an electron pair acceptor (the electrophile). An sp 3 -hybridized electrophile must have a leaving group (X) in order for the reaction to take place.
Nucleophilic Substitution | AQA A Level Chemistry Revision …
A nucleophilic substitution reaction is one in which a nucleophile attacks a carbon atom which carries a partial positive charge. An atom that has a partial negative charge is replaced by the nucleophile. Halogenoalkanes will undergo nucleophilic substitution reactions due to the polar C-X bond (where X is a halogen)

Introduction to Nucleophilic Substitution Reactions
2011年9月26日 · Here are three examples of nucleophilic substitution reactions. What’s the pattern? In each case, we’re breaking a bond at carbon, and forming a new bond at carbon.
Nucleophilic Aromatic Substitution (NAS) - Master Organic …
2018年8月20日 · In Nucleophilic Aromatic Substitution, an electron-poor aromatic ring is attacked by a nucleophile, resulting in a substitution reaction. The reaction proceeds through a negatively charged (carbanion) intermediate. The reaction is accelerated by the presence of electron-withdrawing groups on the aromatic ring.
