Chapter 4, Problem 4.7YT

Interpretation Introduction

Interpretation:

Each unlabeled structure in Figure $\text{4-7}$ is to be labeled as either eclipsed or staggered.

Concept introduction:

In Newman projection formula, when the hydrogen on front carbon covers the hydrogen on the rear carbon, such conformation is called eclipsed conformation, and when the hydrogen atom on front carbon bisects a pair of $\text{C}-\text{H}$ bonds on the rear carbon, it is called staggered conformation. In eclipsed, the atoms are lined up with each other whereas in staggered, they are equally spaced from each other.
