Concept explainers
(a)
Interpretation: The one which changes during a chair flip in case of cyclohexane and the one which remains the same needs to be explained.
Concept Introduction: Chair conformation is the most stable conformation of cyclohexane. It is represented as follows:
Here, the substituted groups in the chair conformation are represented as follows:
The groups showing in straight upward and downward directions are axial, and the groups bend slightly right or left are equatorial.
The axial and equatorial groups are represented in the chair conformation as A and E:
(b)
Interpretation: The change in the group that is up and in axial position in the cyclohexane needs to be explained after the chair flip.
