**Problem:** Which isomer(s) of 2-bromo-1,1,3-trimethylcyclohexane would be most reactive in an E2 elimination? **Structures:** - **I:** Cyclohexane ring with two bromo groups and three methyl groups attached. - **II:** Cyclohexane ring with two bromo groups in a different stereochemistry and three methyl groups. - **III:** Cyclohexane ring configuration with distinct stereochemistry for bromo groups. - **IV:** Similar to III with varied orientation for bromo groups. **Choices:** - A) I - B) II - C) III - D) I and II - E) III and IV **Analysis:** In an E2 mechanism, anti-periplanar geometry is favored for elimination. Analyze each isomer to determine the correct alignment for reactivity.
