Question

**Chemical Structure:**
The structure depicted is a cyclohexane ring with specific substituents:
- A methyl group (CH₃) on the second carbon.
- A bromine atom (Br) on the third carbon.
- Another methyl group (CH₃) on the fourth carbon.
The substituents are arranged as follows:
- The two CH₃ groups are on adjacent carbons, with one oriented above the plane (wedge) and the other below the plane (dash).
- The Br atom is also oriented below the plane (dash).
---
**Instructions:**
Draw the molecule on the canvas by choosing buttons from the Tools (for bonds), Atoms, and Advanced Template toolbars. The single bond is active by default.
**Note:**
Understanding the E1 elimination process implies identifying the beta-carbon that will lose a proton and form a double bond with the alpha-carbon (the carbon attached to the leaving group, Br). The reaction conditions (benzene with heat) facilitate the formation of a carbocation intermediate, leading to the elimination of HBr and formation of a double bond.
