WebThere are various ways to show these orientations. The solid (dark) “up wedge” I used is certainly common. Some people use an analogous “down wedge”, which is light, to indicate a down bond; unfortunately, there is no agreement as to which way the wedge should point, and you are left relying on the lightness of the wedge to know it is “down”. WebElimination Reactions. E2 and E1 Elimination of Cyclohexane Derivatives. In this post, we will talk about the E2 and E1 elimination reactions of substituted cyclohexanes. Let’s start with the E2 mechanism. When the following substituted cyclohexane is treated with sodium ethoxide, an E2 elimination is expected to occur as we have a strong ...

WebOct 20, 2016 · So now we have two sets of rules: If the #4 priority is on a dash: Clockwise = R Counterclockwise = S If the #4 priority is on a wedge, reverse the typical rules: Clockwise = S Counterclockwise = R R and S can easily be assigned to either picture of the molecule. I still encourage you to use a model kit and learn how to do so, however.
