Newman Projection Basics: How To Draw Newman Projections From Line Structures
Newman projections are a way of representing the three-dimensional structure of a molecule on a two-dimensional plane. They are particularly useful for visualizing the relative positions of atoms and groups of atoms in a molecule.Newman projections are drawn by looking down the C-C bond of interest.
The front carbon atom is represented by a dot, and the back carbon atom is represented by a circle. The other atoms or groups of atoms attached to the carbon atoms are drawn as lines or wedges. Lines represent atoms or groups that are in the plane of the paper, while wedges represent atoms or groups that are above or below the plane of the paper.The
relationship between line structures and Newman projections is that a Newman projection can be drawn from any line structure by simply choosing a C-C bond and drawing the projection as described above. Conversely, a line structure can be drawn from a Newman projection by simply drawing the bonds between the atoms or groups of atoms that are represented by lines or wedges.
Newman Projection Conventions
There are a few conventions that are used when drawing Newman projections. First, the front carbon atom is always drawn on the left-hand side of the projection. Second, the bonds to the front carbon atom are always drawn as lines, while the bonds to the back carbon atom are always drawn as wedges.
Third, the groups of atoms that are attached to the carbon atoms are always drawn in the order of their priority. The priority of a group of atoms is determined by the atomic number of the atom that is attached to the carbon atom.
