Question
What are the major products of the reaction below? Draw the curved arrow notation to show the formation of products
The image displays a chemical reaction model involving an E2 elimination reaction. On the left, there is a cyclohexane ring with a bromine (Br) atom attached. The bromine atom is represented with three pairs of lone electrons (dots) around it, indicating its electronegativity and stability as a leaving group.

To the right, there is a hydroxide ion (OH⁻) shown with a negative charge symbol and two pairs of lone electrons around the oxygen atom. This indicates it as a strong base, which is pivotal in facilitating the E2 reaction.

Below these representations, a horizontal arrow points from left to right with the label "E2 Reaction," indicating the process direction. The E2 (bimolecular elimination) reaction involves the removal of the bromine leaving group and a hydrogen atom from an adjacent carbon, resulting in the formation of a double bond, transforming the cyclohexane into an alkene. This transformation occurs when a strong base like OH⁻ abstracts a proton, facilitating the departure of the leaving group simultaneously.
