Chapter 4, Problem 4.47P
Interpretation Introduction

(a)

Interpretation: The given structure is to be converted to a Newman projection around the highlighted bond.

Concept introduction: Conformational isomers are defined as the type of stereoisomers in which the rotation about single bonds forms different spatial arrangements of atoms. It is of two types, eclipsed conformation and staggered conformation.

In Newman projection, the carbon in front is represented by a point and in the back is represented by a circle. It is a visual representation of a conformation. It describes three groups which are attached to each carbon atom in a particular CC bond and the dihedral angle that separates them.
