Here are the essential concepts you must grasp in order to answer the question correctly.
Elimination Reactions
Elimination reactions involve the removal of a small molecule from a larger one, typically resulting in the formation of a double bond. In organic chemistry, common types include E1 and E2 mechanisms, which differ in their steps and conditions. Understanding the type of elimination is crucial for predicting the products and the mechanism involved.

Mechanism of E2 Reactions
The E2 mechanism is a concerted process where the base abstracts a proton while the leaving group departs, leading to the formation of a double bond. This mechanism requires a strong base and typically occurs in a single step. The stereochemistry of the substrate can influence the outcome, making it essential to consider the spatial arrangement of atoms.

Role of Solvents in Reactions
The choice of solvent can significantly affect the rate and outcome of organic reactions. In this case, ethanol (EtOH) serves as a polar protic solvent, which can stabilize ions and facilitate the elimination process. Understanding solvent effects is vital for optimizing reaction conditions and predicting product formation.
