Question

Which are the 2 correct chair conformations of the bond angle?

A) This question is incomplete without specifying the bond and molecules involved.
B) Chair conformations do not involve bond angles.
C) Axial and equatorial positions in a cyclohexane ring.
D) Cis and trans isomers in a double bond.

Answer 1

The chair conformation and the boat conformation are the two correct chair conformations of cyclohexane. The chair conformation is more stable and predominant due to its lower energy and reduced repulsive interactions between hydrogen atoms.

Step-by-step explanation:

The chair conformation and the boat conformation are the two correct chair conformations of cyclohexane. In the chair conformation, all bonds in the cyclohexane ring are 111º, resulting in a bond angle close to the ideal tetrahedral angle of 109.5º. The chair conformation is the more stable and predominant form due to its lower energy and reduced repulsive interactions between hydrogen atoms.
