ELIMINATION REACTION Meaning and
Definition
-
An elimination reaction refers to a chemical reaction in which atoms or groups of atoms are removed from a molecule, leading to the formation of a new double bond or pi bond. It is a type of reaction mechanism commonly observed in organic chemistry.
During an elimination reaction, a reactant molecule experiences the removal of two adjacent atoms or groups of atoms from the same carbon atom. Typically, these atoms or groups are bonded to the same carbon atom through sigma bonds. As a result, a double or pi bond is formed between the two adjacent carbon atoms.
Elimination reactions often proceed through a stepwise mechanism involving the formation of a carbocation intermediate, where the carbon atom loses its four bonds and carries a positive charge. This intermediate is highly reactive and can further react to form the desired product.
There are several types of elimination reactions, with the most common ones being the E1 and E2 reactions. The E1 reaction follows a unimolecular mechanism, as it involves the formation of a carbocation intermediate. On the other hand, the E2 reaction follows a bimolecular mechanism, where the elimination and proton abstraction steps occur simultaneously.
Elimination reactions play a crucial role in the synthesis of various organic compounds, such as alkenes or alkynes. They are also important in understanding the stability, reactivity, and functional group transformations of organic molecules.

Etymology of ELIMINATION REACTION
The word "elimination" derives from the Latin word "eliminare", which means "to turn out of doors" or "to expel". In the context of chemistry, an elimination reaction refers to a type of chemical reaction where a molecule loses specific atoms, groups of atoms, or small molecules to form a new compound. The term "elimination" is used because the reaction involves the elimination or removal of certain components from the starting material to form the desired product.
