Concept explainers
(a)
To draw: The pictorial representation of given molecule as stable chair conformation and to indicate the red group as axial or equatorial.
Interpretation: The pictorial representation of given molecule as stable chair conformation and the indication of red group as axial or equatorial is to be stated.
Concept introduction: The chair conformations are stable forms of cyclohexane and cyclopentane rings as they are free of strain. The substituents present on cyclohexane and cyclopentane rings are arranged at axial and equatorial positions in chair conformation.
