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 …
WebPART II: COMPARING MODEL VS. REAL MOLECULES Use same simulation program, this time, choose "Real Molecules". It may be found at the bottom of the screen. For the electron geometry, write the name of the geometry and draw wedge and dash images to show 3D. For molecular geometry, write the name and also the bond angles. WebAs we've seen, there are a variety of ways to represent molecules in organic chemistry. If any one method is most important to learn, it's the dash-wedge notation, as this will be used throughout this and other books when describing the 3 …
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. WebMar 23, 2024 · In Line-Dash-Wedge notation, when illustrating that an atom or bond is directed towards or away from the viewer (solid triangle for coming forward, dotted lines for going back), does the location of these lines matter when doing illustrations? For example, a THC molecule. The two hydrogen atoms there.
