# How can I draw a Newman projection for cyclohexane?

Dec 11, 2014

A Newman projection for cyclohexane is two Newman projections joined together.

#### Explanation:

For the chair form, view the diagram so that the carbon atom nearest to you ($\text{C-6}$) is "up", $\text{C-2}$ is "behind" $\text{C-1}$, and $\text{C-4}$ is "behind" $\text{C-5}$.

Draw side-by-side projections of the $\text{C1-C2}$ and $\text{C5-C4}$ bonds.

Join the two diagrams with the front carbon ($\text{C-6}$) at the top and the rear carbon ($\text{C-3}$) at the bottom.

Add the groups (here they are $\text{H}$ atoms) to the bonds extending from the Newman projections.

For the boat form, repeat the process.

The difference in this case is that the rear carbon ($\text{C-3}$) is "up" and the bonds are eclipsed.
