Chirality of newman projections
WebD chirality can be used to depict 3-D chirality, if certain ground rules are followed. Thus, Fischer projections and Newman projections simplify 3-D space by projecting three dimensions back to two. One and Two Dimensions Figure 1 illustrates how, in 1-D space, a line segment is achiral, whereas a vector is chiral. It is obvious that in one WebA Newman projection is a convenient way of sighting down a particular carbon carbon bond. In a Newmann projection, the three lines in the shape of a Y represent the three bonds of the first carbon that are sighting …
