Elimination Reactions - IITK

Elimination ReactionsJust as there are two mechanisms of substitution (SN2 and SN1), there are twomechanisms of Elimination (E2 and E1).E2 mechanism bimoleculareliminationE1 mechanism unimolecular eliminationThe E2 and E1 mechanisms differ in the timing of bond cleavage and bond formation,analogous to the SN2andSN1 and SN2 Reactions have some features in common, as do E1 and SN1 removes aproton from the -carbon atom,while the halogen atom leaves from the -carbonresulting in the formation of a -bond.

Thisphenomenon is calledthe Zaitsev Zaitsev product or the more substituted alkene product is more stable than the lesssubstituted product.

Elimination Reactions Just as there are two mechanisms of substitution (S N 2 and S N 1), there are two mechanisms of elimination (E2 and E1). E2 mechanism — bimolecular elimination
