8. Draw both conformations for 1-ethyl-1-methylcyclohexane. Decide which conformation is more stable. 6. Draw the structure for each compound using wedges and dashed wedges a. Cis-1,2-dimethylcyclopropane. b. trans-1-ethyl-2-methylcyclopentane. 9. Label each compound as cis or trans. Draw the second chair conformation. Br H HO HO 10. For cis-1,3-diethylcyclobutane, draw (a). a stereoisomer. (b). a constitutional isomer. 11. For each compound drawn below a. Draw representations for the cis and trans isomers using a hexagon for the six-membered ring and wedges and dashed wedges for substituents c. Draw two possible chair conformations for the trans isomer. Which conformation, if either, is more stable? d. Which isomer,cis or trans is more stable and why?
