Concept explainers
(a)
Interpretation:
A chair conformation of the given molecule with all
Concept introduction:
When the cyclohexane ring is oriented as a chair, all the axial bonds are alternating up and down around the ring and are perfectly vertical. All the equatorial bonds are also alternating around the ring, but are slightly up or slightly down. The structure of cyclohexane in the chair form is shown as:
