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”.

WebMar 13, 2010 · A simple trick: The (R)- (S) Toggle. The difficulty of assigning (R) / ( S) to a stereocenter can be highly dependent on the way the molecule is drawn. For example, assigning the stereochemistry of A should be a cakewalk if you are the least bit familiar with the rules, while B and C are a little more difficult. WebWhenever the lowest priority is going away, the atoms in the front will always be oriented counter clockwise or clockwise. No matter how you move the molecule - highest priority to the front or not, or as in a Newman projection - the rotation of position of 1, 2 and 3 will always be in the same orientation.

WebVideo transcript. - [Voiceover] Let's get some practice drawing chair conformations. One way to do it is to start by drawing two parallel lines that are offset from each other, so let me go ahead and show you what I mean, so here's one line and then here is another line. They're parallel to each other but they're offset a little bit. WebIn all cases, a substituent that was marked by a wedge or a dash in a 2-D drawing will remain that way, but in the chair conformation, the wedge might means axial “up” …
