How to draw newman projections from wedge dash.

It does not matter if we make the Br a wedge or a dash. It is important to mention the fact that there are two β-hydrogens! The number of β-hydrogens is ultimately what explains the stereochemistry of E2 reactions. To demonstrate this, we will use the Newman and sawhorse projections of the alkyl halide participating in the E2 elimination.

Mar 27, 2020 · There are multiple perspectives one can choose when drawing a Newman projection. When drawing a Newman projection, we focus on the conformation of one C-C bond at a time, and ignore all the other conformations. The rotational energy diagram of propane is a sine wave with three maxima, just like ethane. Pretty straightforward, hopefully. The purpose of the Newman projection is that it makes it easy to visualize conformations.
