Chapter 4, Problem 4.19YT

Interpretation Introduction

Interpretation:

All H atoms bonded to the ring in both chair conformations in figure $\text{4-27}$ are to be labeled either as axial or equatorial.

Concept introduction:

In each chair conformation of cyclohexane, one hydrogen atom on each carbon is in an axial position- perpendicular to the plane, and one is in an equatorial position- parallel and pointing outward from the center of the ring. In a chair conformation, six H atoms are at axial positions and six at equatorial position.
