They also provide feedback on the ...Here is one important thing you need to remember when adding the hydrogens or other groups on the zig-zag of the main carbon skeleton. When the zig-zag angle is pointing up, you must point the wedge and dash groups up. When the angle is pointing down, you draw the wedge and dash group down as well: The same principle is applied to larger and ...If drawing a Newman projection does not look like an option you’d take, remember that there is also the swap method for determining the R and S configuration. So, when the lowest priority is neither wedge nor a dash, there is this simple yet such a useful trick making life a lot easier.
