Commonly Tested Lewis Structures
We draw Lewis Structures to predict:
-the shape of a molecule.
-the reactivity of a molecule and how it might interact with other molecules.
-the physical properties of a molecule such as boiling point, surface tension, etc.
Drawing the Lewis Structure for CO
Video: Drawing the Lewis Structure for CO
For the CO Lewis structure, calculate the total number of valence electrons for the CO molecule. After determining how many valence electrons there are in CO, place them around the central atom to complete the octets.
The Lewis structure for CO has 10 valence electrons.
For the CO Lewis structure you'll need a triple bond between the Carbon and Oxygen atoms in order to satisfy the octets of each atom while still using the 10 valence electrons available for the CO molecule.
It is helpful if you:
- Try to draw the CO Lewis structure before watching the video.
- Watch the video and see if you missed any steps or information.
- Try structures similar to CO for more practice.
