Why is the boat conformation less stable?
Correspondingly, why is the chair conformation more stable than boat?
Chair conformation of cyclohexane is more stable than boat form because in chair conformaion the C-H bonds are equally axial and equatorial, i.e., out of twelve C-H bonds, six are axial and six are equatorial and each carbon has one axial and one equatorial C-H bond.
Additionally, which conformation of cyclohexane is least stable? The half chair form is least stable due to maximum strain. It is 10kcal/mol less stable than the chair form and is least stable. The twist boat conformation has less steric and torsion strain as compared to half chair conformation and It is 5.5kcal/mol less stable than the chair form.
Similarly, you may ask, which conformation is more stable?
In terms of stability, the staggered conformation is more stable than the eclipses. This is for two reasons: 1) Steric hindrance. In the eclipsed conformation, the positioning of the atoms forces them closer together, increasing the amount of steric strain in the molecule.
Which conformation of cyclohexane is more stable?
The chair conformation is the most stable conformation of cyclohexane. A second, much less stable conformer is the boat conformation.
