There are 3 types of Elimination Reaction. They are:
– E1 type – E2 type and – E1cb type
An Elimination Reaction is an organic reaction in which two substituents are removed from a molecule to form a product.
The reaction takes place either through heating or in the presence of acid, base or metals.
E1 type has two steps namely Ionisation and Deprotonation. It happens in the presence of a base.
It is known as unimolecular elimination and it exhibits first-order kinetics.
Here, the rate is directly proportional to the concentration of the substance to be transformed.
E2 type involves a one-step mechanism and is also known as bimolecular elimination. It exhibits second-order kinetics.
The reaction rate varies directly with the concentrations of both the eliminating agent and the substrate.
E1cb type is also a two-step mechanism. It is a unimolecular conjugate base elimination.
