"WebThe twist-boat conformation was determined to be the lowest energy conformation for cis-1,4-di-tert-butyl-cyclohexane, with a global energy minimum of 23.977 kcal/mol. This is the most stable conformation for the molecule because both of the large tert-butyl substituents are in equatorial positions, which is of high priority for this type of molecule.

WebMore twist will help keep the boat upright. The boat will typically have to sail at wider angles (foot) to have the power necessary to blast through waves, and that will generate more heel. WebTwist-boat/Chair: 14 kJ/mol. So yes, there's a decent stabilization in the twisted form of the twist-boat. You have to get the hydrogens right, or you'll end up with a bunch of eclipsed …

Webof the boat can be relieved by twisting. The twist boat conformation is about 5 kcal/mol (21 kJ/mol) less stable than the chair conformation. Figure 6.11 also shows that there are two different types of hydrogens, called axial hydrogens and equatorial hydrogens, in the chair conformer of cyclohexane. The axial Webhexane, and it is the transition state for the interconversion of the chair and twist-boat confor-mations. (Notice the position of this conformation on the energy diagram of Fig. 7.5.)
