WebFischer Projections provide aid in visualizing chirality as well as where substituents are oriented within space which is why their application can be useful to many. Chirality … Web1) Determine if the Newman projection is going to have the “Y” shape or the upside-down “Y” shape. In this case, it is going to be the “Y” shape since there are two groups pointing up and to the sides (H and Cl). We are talking about the front carbon shown in red. 2) You can now identify the groups pointing to the left or to the right.
