Newman projection

The Newman projection, which was introduced by Melvin Spencer Newman is one of several ways to represent a molecule as two-dimensional three-dimensional structure. In this process the resulting molecule along a selected single bond is considered.

Use

The Newman projection is suitable for the representation of the conformation of a molecule. One differentiates between different conformers of alkanes, also rotamers by their torsion angles. It is also suitable for the description of reaction mechanisms and the prediction of the stereochemistry of a reaction product, for example by the Cram's rule.

Other modes of representation

  • Sawhorse projection
  • Fischer projection
  • Wedge -dash notation
  • Haworth projection
