3.1.2 The conformations of cycloalkanes
Construct a model of cyclohexane (C6H12), a six-membered ring of carbon atoms with two
hydrogen atoms attached to each carbon atom.
Is the ring planar or puckered?

The cyclohexane ring can be arranged in many forms. The two major forms are commonly
called the chair conformation and the boat conformation. For instance in the chair
conformation; consider the two hydrogen atoms at each carbon. One C-H bond is roughly in
the mean plane of the molecule and one C-H bond is roughly perpendicular to that plane.
These two positions are referred to, respectively, as equatorial and axial, as shown below.
