Chair Boat Twist Conformation
The twist-boat conformation, sometimes called twist (d 2 symmetry) can be derived from the boat conformation by applying a slight twist to the molecule about the axes connecting the two unique carbons.. Cyclohexane’s chair, twist and boat conformations repeat the process with cyclohexane, but make sure the optimization limit is set to normal. the greater flexibility of this molecule will be evident by the fact that marvinsketch finds several conformations. the lowest energy form is the most important.. Cyclohexane can also exist in a boat conformation, shown in figure 2.9. like the chair conformer, the boat conformer is free of angle strain. however, the boat conformer is not as stable as the chair conformer because some of the bonds in the boat conformer are eclipsed, giving it torsional strain..
A third conformation is produced by twisting the boat to give the twist or skew-boat conformation. the twist relieves some of the torsional strain of the boat and moves the flagpole h further apart reducing the steric strain. consequently the twist boat is slightly more stable than the boat.. Carbohydrate conformation refers to the overall three-dimensional structure adopted by a carbohydrate molecule as a result of the through-bond and through-space physical forces it experiences arising from its molecular structure..
