How to draw newman projections from wedge dash.

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.

It is then held in the vertical plane in such a manner that the two groups pointing upwards are away from the viewer, i.e. both these groups are shown on the vertical line. Such a conversion for 2,3-dibromobutane is shown.

Hint: Using wedge and dash notation, solid lines (sticks) represent chemical bonds in the plane of the surface. Black wedges represent chemical bonds coming toward you, while dashed lines are for bonds that extend back behind the surface. .We must view a wedge-dash formula from the correct angle to convert it to a Fischer projection.

A wedge and dash projection is a way of writing organic molecule to represent three dimensional structures. The Wedge-shaped line represents bonds oriented towards the viewer and Dash line shows bonds pointing away from viewer. The Solid lines show that bonds are in the plane of the paper.
