Draw the most stable chair conformation of cis-1,3-diisopropylcyclohexane
Steps:
1. Draw a cyclohexane and number it. Attach isopropyl group to carbon 1 and another isopropyl group to carbon 3. Cis means you need to put both groups either on a wedge or on a dash.
2. Next, draw two chair conformations and number them properly. Attach isopropyl to carbon one and another isopropyl to carbon three in each chair conformation. If you drew both of them on a wedge, attach them UP on both chairs. Dash would mean down.
Use the guideline below for up and down positions on both chairs.
3. Label each group attached to a chair as either axial or equatorial. Axial groups are straight up or straight down. Equatorial groups are at an angle.
4. One chair has both groups in axial positions and another chair has both groups in equatorial positions. The chair that has most groups in equatorial positions is the most stable chair.
