Practice Problem: E2 on Cyclic Systems and Cyclohexane Chairs

The video tutorial explains the E2 elimination reactions of two stereo isomers with a bromo and TERT butyl group. It highlights the difference in reaction speed between the cis and trans isomers due to their chair conformations and thermodynamic stability. The cis isomer reacts faster because its favorable conformation allows for easier proton extraction, while the trans isomer's unfavorable conformation slows the reaction. The tutorial emphasizes the importance of anti-periplanar arrangement and the role of steric hindrance in determining reaction dynamics.

What are the two stereo isomers discussed in the reaction?

Explain why the E2 elimination reaction is faster for the cis isomer compared to the trans isomer.

What is the significance of the axial position of the leaving group and beta proton in E2 elimination?

Describe the role of the tert-butyl group in the stability of the molecule during the elimination process.

How does the distribution of conformations in solution affect the rate of the E2 elimination reaction?
