The nice thing is$,$ we don't need to include all of these H$\text{'}$s on our chair conformations. Feel free to remove all of

those hydrogens, and let's put on a couple of other groups: a methyl, alcohol, and halogen. $($HINT: Feel free to just use a

different color for each group, we don't have to actually make the "real" structure.$)$

After building out chair $1,$ draw out the planar form $($using only wedges$/$dashes$)$ when the molecule is viewed from the

top.

Next, perform a "chair twist" to get the other chair conformation. Draw these groups onto the blank chair $2$ above. Now,

draw the planar form of this new chair. Compare the two planar forms, like we did before...

You should be observing a few things here: The planar form $($which doesn't show axial$/$equatorial positions$)$ should be

identical for both conformations. The two chair forms, however, will seem different. One will have more equatorial

groups than the other. Identify the more stable chair conformation, which should have more equatorial groups.

Now, try out some of the practice problems below. Feel free to use the model kits as much $($or as little$)$ as you need. For

each problem, draw out: Both chair flips and the planar form $($one of those will be given to you$).$ You should also identify

which chair conformation is the more stable form!
