Chapter 4, Problem 4.3P

Interpretation Introduction

Interpretation:

The Newman projections for each ${60}^{{}^{\text{o}}}$ rotation about $\text{C-C}$ single bond, from ${\text{-180}}^{{}^{\text{o}}}$ to ${\text{+180}}^{{}^{\text{o}}}$ is to be drawn.

Concept introduction:

In a Newman projection, the bond of interest is not visible. The two atoms are directly connected by the bond of interest. It is imagined that the front and back carbons. The front carbon atom is shown as a point while the back carbon atom is shown as a circle. The atoms attached to the front carbon converge at the point while the atoms attached to the back carbon are shown connected to the circle.
