An elimination reaction is a type of organic reaction in which two substituents are removed from a molecule in either a one or two-step mechanism.[2] The one-step mechanism is known as the E2 reaction, and the two-step mechanism is known as the E1 reaction. The numbers do not have to do with the number of steps in the mechanism, but rather the kinetics of the reaction, bimolecular and unimolecular respectively. In cases where the molecule is able to stabilize an anion but possesses a poor leaving group, a third type of reaction, E1CB, exists. Finally, the pyrolysis of xanthate and acetate esters proceed through an "internal" elimination mechanism, the Ei mechanism.

when haloalkane with b-hydrogen atom is heated with alcoholic solutio of potassiumhydroxide there os elimination of hydrogen atom from beta carbon and a halogen atim from the alpha-C atom .
As a result an alkene is formed as a product .
Since b atom is involved in elimnation its often called beta elimination
-C-CX- + BASE ----> C=C + (BASE)H +X`
