Draw the most stable structure of cis-1-tbutyl-2-methylcyclohexane. Your structure should clearly distinguish between axial and equatorial positions.

Which isomer is more stable, trans-decalin or cis-decalin? Explain. Make sure your structure is clearly drawn with equatorial and axial bonds clearly delineated.

5) (10 pts) Draw the 2 chair conformations of each compound and label the substituents as axial or equatorial. In each case determine which conformation is more stable. Make sure that your drawings show the correct equatorial or axial orientation. If it is not clear, it is wrong! a) cis-1-ethyl-2-isopropyleyclohexane b) cis-1-ethyl-3-metylcyclohexane c) cis-1-ethyl-4-methylcyclohexane d) trans-1-ethyl-2-isopropylcyclohexane e) trans-1-ethyl-3-metylcyclohexane

Which of the following describes the most stable conformation of trans-1-tert-butyl-3-methylcyclohexane? Both groups are equatorial. The tert-butyl group is equatorial and the methyl group is axial. Both groups are axial. The tert-butyl group is axial and the methyl group is equatorial. none of the above
