Answer:
Straight line shows that the outside atom is in the same plane as the central atom. Dashed lines shows that the outside atom is farther from us than the central atom. (Going into the page). Wedged line shows that the outside atom is closer to us than the central atom. (Coming out of the page)
Step-by-step explanation:
When showing the 3D structure of molecules, we use dashes, wedges, and straight lines. Below are the functions of each line.
- Straight lines: Straight lines are used to show atoms and bonds that are in the same plane as the central atom.
- Dashed lines: Dashed lines are used to show atoms and bonds that go into the page, behind the plane, away from you. That is this line shows that the outside atom is farther from us than the central atom.
- Wedged lines: Wedged lines show bonds and atoms that come out of the page, in front of the plane, toward you. It shows that the outside atom is closer to us than the central atom.
