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 H2O2
When you are learning to draw Lewis Structures you will see this one frequently. Be sure to make sure you are able to draw the structure for H2O2 quickly and accurately!
H2O2 is also called Hydrogen perxoide.
The Lewis Structure for Hydrogen perxoide is useful because it allows to determine the molecular geometry and the polarity of the molecule. Because of the two lone pairs on each Oxygen atom, H2O2 will have a bent molecular geometry with respect to each Oxygen atom.
Remember that Hydrogen only needs two electrons to have a full outer shell.
Video: Drawing the Lewis Structure for H2O2
It is helpful if you:
- Try to draw the H2O2 Lewis structure before watching the video.
- Watch the video and see if you missed any steps or information.
- Try structures similar to H2O2 (like HCl or CH4) for more practice.
