shapes_en.html
You will complete a full lab report as done for CHEM 1411 in your manual. You will include your objective, materials and equipment, procedure, safety, data, observations and analysis.
Molecular Shapes Lab: 1)
Click on “Real Molecules” and go to the page:
2)
Make sure that “Real” is selected, and Molecule Geometry, Electron Geometry, Show Lone Pairs and Show Bond Angles are all checked..
3)
Fill in the data table for the molecules listed below in the website. To assist you an example has been done below. Do not do the other molecules on the sheet

Be sure to include any specific observations for your molecules after your data table.
Analysis: Answer the following questions in complete sentences.
1)
In molecules with the same number of electron groups but different molecular geometries, discuss what happens to the bond angle?
the bond angle will vary
.
2)
What happens to the bond angle as you increase the number of bonding groups?
a smaller bond angle
.
3)
What is the difference between tetrahedral bent and trigonal planar bent?
if a molecule has 3 bonds and 0 lone pairs, it is trigonal planar.
If a molecule has 3 bonds
and 1 lone pair, it is bent or angular.
If a molecule has 4 bonds and 0 lone pairs, it is tetrahedral
.
4)
What is the difference between CO

? The difference between H

5)
How is trigonal pyramidal different from trigonal planar?
For trigonal pyramidal, there is a
lone pair
at the central atom and the bond angle is at around 107, while for trigonal planar, there is no lone pair electrons at the central atom and the bond angle is around 120.
6)
Imagine that this lab was done with real models instead of computer simulations. Discuss 3 sources of uncertainty for the experiment.

Go to the interactive. Use the Single Collision tab to represent how the collision between monatomic oxygen (O) and carbon monoxide (CO)results in the breaking of one bond and the formation of another. Pull back on the red plunger to release the atom and observe the results. Then, click on “Reload Launcher” and change to “Angled shot” to see the difference.(a) What happens when the angle of the collision is changed?(b) Explain how this is relevant to rate of reaction.

Choose the "Playground" option to complete this modeling activity: You can drag and drop molecules to the screen and put them
together then click the 3D button to see a model like the one we would make in the classroom. Make sure to check the ball & stick model
mode in 3D viewer- this is important for seeing the bonds (sticks)!
1. Build the molecule (you can see different element choices by clicking the dots at the bottom of the screen)
2. Draw the Lewis structure.
3. Count the number of bonds and lone pairs on the central atom (lone pairs are not shown on the models only on your Lewis Structure)
4. Use bond and lone pair information to determine the shape of the molecule (linear, bent, trigonal planar, tetrahedral)
4. Calculate the polarity of each different bond by subtracting atom electronegativities.
5. Use the bond types and shape to determine if the molecule is polar or…
