It is difficult on a flat piece of paper or screen to draw a three‐dimensional shape. Most molecules are three‐dimensional with bonds that point in different directions. Chemists use many different ways of showing three‐dimensional structures, but in this book we will use single lines, wedges, and dashed lines. Each type of line means something slightly different and gives important information about the location and direction of the bond in space. The single line means that the bond is in the plane of the page; the wedge means that the bond is coming out of the page towards you; and the dash means that the bond is going into the page, away from you.

The different representations of bonds in a molecule.
