In order to better visualize different conformations of a molecule, it is convenient to use a drawing convention called the Newman projection. In a Newman projection, we look lengthwise down a specific bond of interest – in this case, the carbon-carbon bond in ethane.
A Newman projection is a drawing that helps visualize the 3-dimensional structure of a molecule. This projection most commonly sights down a carbon-carbon bond, making it a very useful way to visualize the stereochemistry of alkanes.
What are Newman Projections? Newman projections are drawings used to help visualize the 3-dimensional structure of an organic molecule.
But since that's a little bit messy, normally when people draw a staggered projection-- an eclipsed conformation, as a Newman Projection. Instead of directly eclipsing that last, that back hydrogen, they'll put it to the right a little, or they'll push it off a little bit.
A Newman projection is a representation of the molecule looking through a C-C single bond. For every Newman projection, you need to specify the bond and the direction you are looking at. For example, for our molecule, we can look through the C1-C2 bond (even though it can be through any bond).
Newman projection represents a molecule’s conformational arrangement from a specific viewpoint. Our viewpoint is directed along a particular bond of interest: the carbon-carbon sigma bond in hydrocarbons.
