Newman Projection and Sawhorse Projection

Newman Projection: In this projection, the molecule is observed along with the central carbon-carbon bond, a circle is drawn, and the center of the circle represents the front carbon. The front carbon is drawn from the center of the circle while the back carbon is drawn from the periphery.
