Draw the conformed out of which an E2 elimination reaction can occur?

Q8. Draw the two possible chair-like conformations of compound 1. Using the Çabo LAgld erelog priority rules, assign the absolute stereochemistry to each stareogenic centre contained in compound 1. NH2 'F 1

2) Draw Newman projections of all staggered conformations of (S)-butan-2-ol. Clearly mark the highest energy conformation. 3) Draw both chair conformations of (1S,3R)-1-chloro-3-isopropylcyclohexane. Clearly mark the most stable conformation, and also the conformation which enables E2 elimination.
