A solid triangle showing a bond coming towards the reader.
Also known as: Bold wedge, Stereochemical wedge
A solid wedge, narrow at the atom and widening outwards, shows a bond projecting towards the viewer. It is one half of the convention that turns a flat drawing into a three-dimensional claim, and the narrow end must be at the stereocentre for the drawing to be unambiguous.
Shows a bond projecting out of the plane of the paper towards the reader, drawn as a solid triangle.
Contexts: Laboratory
Must be drawn with its point at the stereocentre, since a wedge widening the wrong way makes the configuration ambiguous.
Contexts: Laboratory
A solid triangle joining two atoms, narrow where it meets one and broad where it meets the other.
