Consider C6H12 (cyclohexane) model. The following shapes are two possible conformations of cyclohexane.
Adjust your model to fit chair conformation. Are the C-H bonds in the chair conformation staggered or eclipsed?
Use drawing to explain your observations: Flip the chair conformation into a boat conformation. Are the C-H bonds in the boat conformation staggered or eclipsed? Use drawing to explain your observations: From examination of the models, which conformation is more stable? Why?
