"WebAug 18, 2024 · The Fischer-Rosanoff convention gives rise to uncertainties with molecules with more than one chiral center. For example, considering D- (+)-glucose, the D-L system gives information about the configuration of C-2, but no information about the other asymmetric centers, namely, C-3, C-4, and C-5. In these cases, the RS system, … " - Determining chirality of fischer projections

WebNov 9, 2016 · I would think carbon 4 is "into the page" as it is further away from our point of view (which matches the Fischer projection, as it is drawn vertically there). Based off this, carbon 2 would also be into the page (as its the same as Carbon 4 in the Fischer projection). Hence, the $\ce{OH}$ and $\ce{H}$ would be out of the page.
