Homework Answers
Well a simple one word answer for this question is
-Torsional strain
now the explanation
There are basically 2 types of strains in the cyclohexane conformers one is angle strain and other one is torsional strain
The angle strain is present in both the conformers that is chair and boat but the torsional strain is absent in the chair conformation
Torsional strain is doe to the repulsive force between 2 atoms which are not joined directly to one another
Since in chair formation the structure is staggered so no 2 non connected atoms repel each other strongly and the torsional strain becomes absent
I hope this helps. If you have any query or want more detailed explanation, feel free to ask in the comments section below.

Problem #9. In addition to the chair conformations, cyclohexane derivatives also have half-chair, twist boat, and boat conformations. These are all higher energy than chair conformations. In fact, the half- chair is the transition state between the chair and the twist boat, and the boat is the transition state between two different twist boat conformations.

How does ring strain change with ring size? Explain. (for cycloalkanes: cyclopentane, cycohexane chair, cyclohexane twist boat and cycloheptane.) Estimate the contributions of torsional strain and angle strain to the energy of each cycloalkane: (cyclopentane, cycohexane chair, cyclohexane twist boat and cycloheptane. . guide your estimate of torsional strain for gauche and eclipsed interactions.
