What is Dash wedge notation?

wedge-and-dash (uncountable) (chemistry) A method of representing the three-dimensional structure of a molecule in which simple lines represent bonds in the plane of the image, wedge-shaped lines represent bonds towards the viewer, and dashed lines represent bonds away from the viewer.

Are Newman projections chiral?

Looking at the Newman projection taken along the central C-C bond, we can see that the molecule possesses a center of inversion and therefore is not chiral, despite the fact that it has two stereocenters (where a stereocenter is a carbon with four different substituents attached).

How to draw wedge and Dash structure from Newman projection?

Here’s how to convert the wedge – dash structures to Newman Projections. Draw two Newman projection templates. Draw two circles. Put a dot in the centre of each. On one circle, draw a Y with the spokes radiating from the dot at 120° angles.

Is the Sawhorse representation the same as the Newman projection?

The sawhorse representation combines the wedge and dash model and the Newman projections. It extends out the bond on the Newman projection, like on a wedge and dash model, but keeps the bonds lined up so that we can see the interactions easier.

Which is the most stable wedge or Newman projection?

So, the 1st and 3rd projections (the ones where one oxygen is up and the chlorine is down, or vice versa) are the most stable. So, the wedge and dash models best show the 3D molecule and the Newman projections best show the interference between bonds.

What kind of Science is the Newman projection?

Laura has a Masters of Science in Food Science and Human Nutrition and has taught college Science. By looking at something from multiple perspectives we can understand different things about it. In this lesson we will learn about the Newman projections, the sawhorse representations, and the wedge and dash models for representing chemical molecules.
