WebTools. In chemistry, a nucleophilic substitution 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 ). The molecule that contains the electrophile and the leaving functional group is called the ...

In this reaction, a substrate (typically an alkyl halide) eliminates one equivalent (unit) of acid to form an alkene. Two possible mechanisms are available for this elimination reaction – E1 and E2 mechanisms. mary lou newman obituary

Bimolecular nucleophilic substitution (S N 2) reactions constitute one of the most widely-used organic chemistry reactions, both in chemistry and biology. 1 The general reaction … WebSN2 Reaction. The SN2 reaction is a bimolecular nucleophilic substitution reaction that occurs in one step. The nucleophile performs a backside attack on the carbon to which the leaving group is attached. If the carbon is asymmetric, inversion of stereochemistry is … mary lou neff
