Introduction

Newman projections are a crucial tool in organic chemistry, particularly in the field of stereochemistry. They provide a two-dimensional representation of a molecule's three-dimensional structure, allowing chemists to visualize and analyze the spatial arrangement of atoms and functional groups. However, drawing Newman projections can be a time-consuming and tedious process, especially for complex molecules. Fortunately, there are several free software programs available that can help you create accurate and detailed Newman projections.

What is a Newman Projection?

A Newman projection is a two-dimensional representation of a molecule's three-dimensional structure, viewed along a specific bond. It is a projection of the molecule's structure onto a plane, with the bond of interest perpendicular to the plane. Newman projections are commonly used to visualize the conformation of a molecule, including the arrangement of atoms and functional groups around a specific bond.
