- A dash is used to represent a bond in chemistry, and it represents a pair of electrons1. Dashes are used to represent bonds and atoms going backward from the backbone plane23. In dash-wedge structures, all atoms and bonds are shown2. Non-bonding electron pairs are generally not shown, except when useful for understanding a molecule's properties and behavior2. Wedge-and-dash is a method of representing the three-dimensional structure of a molecule in which simple lines represent bonds in the plane of the image, wedge-shaped lines represent bonds towards the viewer, and dashed lines represent bonds away from the viewer4.Learn more:✕This summary was generated using AI based on multiple online sources.
