Many others, though, are composed of sp3-hybridized atoms, and it is these cyclic structures that are the topic of discussion in this section.

However, this strain, together with the eclipsing strain inherent in a planar structure, can be relieved by puckering the ring. Cyclohexane is a good example of a carbocyclic system that virtually eliminates eclipsing and angle strain by adopting non-planar conformations.

In all cases, a substituent that was marked by a wedge or a dash in a 2-D drawing will remain that way, but in the chair conformation, the wedge might means axial “up” instead of equatorial “up” depending on whether it is a right- or left-handed chair.

In the case of the hydrocarbons (Me, Et, iPr, tBu), we see that there is a slight increase in energy as one proceeds from Me to Et to iPr, but then there is a big jump in A-value for tBu.
