WebUnimolecular Elimination (E1) is a reaction that results in the formation of a double bond by removing an HX substituent. It is identical in different ways to the unimolecular nucleophilic substitution reaction ( S N 1 Reaction ). The formation of a carbocation intermediate is one of the similarity. E1 is a model to explain a particular type of chemical elimination reaction. E1 stands for unimolecular elimination and has the following specifications • It is a two-step process of elimination: ionization and deprotonation. • E1 typically takes place with tertiary alkyl halides, but is possible with some secondary alkyl halides.
