How To Draw Newman Projections

In the video below ive distilled the process for doing this and i guide you through two examples.

How to draw newman projections. For example for our molecule we can look through the c1 c2 bond even though it can be through any bond. The six carbon hydrogen bonds are shown as solid lines protruding from the two carbons. Newman projections if youre seeing this message it means were having trouble loading external resources on our website. In a newman projection we look lengthwise down a specific bond of interest in this case the carbon carbon bond in ethane.

Determine which two carbon atoms are being studied. We depict the front atom as a dot and the back atom as a larger circle. For every newman projections you need to specify the bond and the direction from which you are looking. Add an eye with an arrow looking down the carbon carbon bond being studied.

A newman projection focuses on one specific bond of the molecule and note which atoms are attached to these carbon atoms. Once youve mastered the art of naming alkanes sooner or later in organic chemistry youre going to have to draw newman projections. When drawing newman projections look at the molecule from a different perspective by looking down two of the carbon atoms so you can only see the front carbon atom and not the back carbon as it is blocked by the front carbon. And not just draw them but convert between them and line bond aka bond line or zig zag structures.

Newman projections newman projections are drawn by looking directly along a particular bond in the system here a c c bond and arranging the substituents so that they are equally spaced around the atoms at each end of that bond. 2 3 means looking down the carbon 2 and carbon 3 bond. And this is what we call newman projections. This organic chemistry video tutorial shows you how to draw newman projections from bond line structures viewed along the c2 and c3 bond.
