WebUsually, we look at a Fischer projection so one of the vertical bonds to a chiral carbon is in the plane of the paper. Then, the vertical bonds above and below that bond are behind … WebFischer projections are commonly constructed beginning with a sawhorse representation. To do so, all attachments to main chain carbons must be rotated such that resulting Newman projections show an eclipsed configuration. The carbon chain is then positioned vertically upward with all horizontal attachments pointing toward the viewer. tsa west palm beach airport
