How to draw newman projections from wedge dash.
Much like the Dash-Wedge representation, the Newman projection precludes that the spatial arrangement of atoms and molecules within the compound is dependent upon the specific bonds linking these groups and the relative position (i.e., bond angle) of these bonds in relation to the entire compound. In other words, as full rotation around the ...

It is an end-on representation where the molecule is viewed along the bond of interest, a projected bond. The atom farther from the observer is represented by a circle, and the atom closer to the observer is denoted as the center of the circle. 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. To figure that out draw both reactions and determine which structure has more R groups connected to the alkene the one with the more R groups is the most stable making it the major contributor. ...
