The twist boat conformation is the preferred conformation for this compound.

Question

Quizplus · Accepted Answer

The cis-1,4-Di-tert-butylcyclohexane has two tert-butyl groups (bulky groups) located in the axial positions when it is in the chair conformation. In order to relieve the steric strain, the molecule adopts the twist boat conformation, in which the tert-butyl groups are in a more stable equatorial position. The other options do not have two bulky groups in axial positions that require this conformational change.
