How to draw newman projections from wedge dash.
To show stereochemistry, we must use wedge-dash formulas. These formulas give the stereochemical information. But it is easiest to compare structures using Fischer projections, because they are always written in the same way. If we make the wedge-dash formula vertical with C-1 at the top, it becomes structure B above.
