Elimination reactions are a type of chemical reaction where two atoms or groups are removed from a molecule, resulting in the formation of a double bond or a ring structure. These reactions often occur in organic chemistry and are important for creating more complex molecules. A common example is the dehydrohalogenation reaction, where a hydrogen atom and a halogen atom are eliminated from an alkyl halide, leading to the formation of an alkene. In elimination reactions, the process can be classified into two main types: E1 and E2. The E1 mechanism involves a two-step process where the leaving group departs first, forming a carbocation intermediate, followed by the removal of a proton. In contrast, the E2 mechanism is a one-step
