Bold structure on chem draw
Here, note that it actually doesn’t matter if the “wedged” bond (C) is drawn to the left or to the right of the “dashed” bond – they depict the same molecule! Here is what you might call the “industry standard” version, since it will easily allow us to add chains going off to the left and right (more on that later). The “Industry Standard” Way To Draw Tetrahedral CarbonĪlthough there are several permissible ways to depict a tetrahedral carbon on a flat page using dashes and wedges, the most intuitive to grasp is the one which shows one bond on a “wedge”, one on a “dash”, and two that are “flat” (that is, in the plane of the page). Think of artists depictions of a mountain range: the further away they are, the more faintly they are drawn. The way it’s done in chemistry is with heavy “wedges” to depict bonds in the foreground (pointing out of the page) and light “dashes” to depict bonds in the background (behind the page).

One of the challenges that has faced chemists since the days of Van’t Hoff’s controversial ( for the 1870’s!) proposal that carbons attached to four substituents can adopt a tetrahedral geometry is that of trying to depict three-dimensional structures on a two dimensional page. And some very common pitfalls that might not be immediately obvious. There is a knack to drawing proper tetrahedrons.
