Draw the most stable chair conformation of cis-1-ethyl-2-methylcyclohexane
Steps:
1. Draw a cyclohexane and number it. Attach ethyl to carbon 1 and methyl to carbon 2. 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 ethyl to carbon one and methyl to carbon two 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. Both chairs have one axial and one equatorial group. However, since ethyl is a bigger group, it prefers to be equatorial.
