Fischer projections r and s
WebR and S configuration on Newman projections To determine the R and S configuration of a chiral carbon in Newman projections, we need to look through the bond such that the lowest priority group is pointing back. But first, one question – why would anyone need to determine R and S on a Newman projection, right?
