The Newman projection consists of a circle or a point that represents the carbon-carbon bond and two lines which represent the substituents attached to each carbon atom. In contrast, the wedge and dash notation uses solid wedges and dashed lines to indicate whether a substituent is coming out of or going into the plane of the paper, respectively.4. Putting It Together: The Mechanism Of The E2 Reaction. Here's a hypothesis for how this elimination reaction works. It accounts for all the bonds that form and break, as well as the rate law, and - crucially - the stereochemistry. In this mechanism, the base removes the proton from the alkyl halide that is oriented anti to the leaving ...In a Fischer projection drawing, the four bonds to a chiral carbon make a cross with the carbon atom at the intersection of the horizontal and vertical lines.

In order to better visualize these different conformations, 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. We depict the 'front' atom as a dot, and the 'back' atom as a larger circle.

So as a Newman Projection the front's going to look the same. You have a hydrogen there, you have this hydrogen, you have that hydrogen, and then you have that blue, or I guess that purple hydrogen, down here. So that's the front of it. But the back, they're right behind it's. So let me draw the back carbon. There's a tap for that.
