SN1 Mechanism - an overview ScienceDirect Topics

WebThe E1 mechanism is nearly identical to the S N 1 mechanism, differing only in the course of reaction taken by the carbocation intermediate. As shown by the following equations, a carbocation bearing beta-hydrogens may function either as a Lewis acid (electrophile), as it does in the S N 1 reaction, or a Brønsted acid, as in the E1 reaction. In chemistry, a racemic mixture, or racemate , is one that has equal amounts of left- and right-handed enantiomers of a chiral molecule or salt. Racemic mixtures are rare in nature, but many compounds are produced industrially as racemates.
