Sapling Chapter 2 #40 Newman Projection

The Newman Projection on the left displayed the stereochemistry of a conformer. The Newman projection in this problem displayed a staggered formation, which is the most stable compared to the eclipsed form. There are two major carbons here. One that holds the halogen Br, I, and Cl and the other F and hydroxide and a hydrogen. If we look at the stereochemistry carefully, the wedge-and-dash drawing, we know that Br is trans to H, OH is trans to Cl, and F is trans to I. This labeled them as opposite to each other. The back carbon cannot be seen, but it has the Br, Cl, and I; therefore only the front-facing carbon can be seen through the Newman projection.
