Practice Problem: E2 on Cyclic Systems and Cyclohexane Chairs

9th - Higher Ed
For this one we will want to recall some of the rules about doing E2 on a cyclohexane ring, as well as the relative stabilities of cyclohexane chairs. Combining concepts! Predicting kinetics!

Practice Problem: Hydrogenation, Isomerism, and Cyclohexane Chairs

9th - Higher Ed
For this one we need to understand the stereospecificity of hydrogenation over platinum metal, stereochemical relationships, and the relative stability of cyclohexane chair conformations.
