1. Now construct cis-1,2-dimethylcyclohexane in the chair conformation and draw it. Perform the ring flip and draw that conformation. Which of the two conformations is preferred? This compound is meso, find the conformation that accounts for this? 2. Construct and draw trans-1-ethyl-2-methylcyclohexane in the chair conformation. Perform the ring flip and draw that conformation. Which conformation is preferred/most stable? Why? Construct and draw the cis isomer in the most stable chair conformation. Perform the ring flip and draw that conformation....
Draw 1,4 -Dimethylcyclohexane in hawthorne projection first, then show it in chair conformation in cis then show it flipped. Also, then show it in chair conformation in trans and then show it flipped.
