Why is the chair conformation the most stable?
Consequently, 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.
Similarly, which chair is more stable? The chair conformation is the most stable conformation of cyclohexane. A second, much less stable conformer is the boat conformation. This too is almost free of angle strain, but in contrast has torsional strain associated with eclipsed bonds at the four of the C atoms that form the side of the boat.
Likewise, people ask, why is the chair conformation more stable than the 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.
Why is Equatorial more stable?
When substituents are in the equatorial position, they are farther away from each other. This increases the stability of the conformation. In the pictures below, the methyl in the equatorial position is more stable because it avoids interaction with the hydrogen atoms.
