In the next chapter we'll look at cycloalkanesâ€”saturated cyclic hydrocarbonsâ€”and weâ€™ll see that the molecules generally adopt puckered, nonplanar conformations. Cyclohexane, for instance, has a puckered shape like a lounge chair rather than a flat shape. Why?
In each case below, identify the higest and lowest energy conformations. In cases where two or three conformations are degenerate, choose only one as your anwser. Use Me, H, and Et when drawing the structures.
