Organic Chemistry
Name _____________________________
Making molecules more visible (Hydrocarbons and functional groups)
Purpose: Use a molecular model kit to make a ball and stick/spring model of an organic molecule
provided by your instructor (Day 1) then identify the molecules (Day 2).
Materials: Ball and stick molecular models
Procedure:
1. Use the molecular model set given to your group to build the molecule given to you by your instructor.
2. Check with your teacher when you have completed your molecular structure to make sure it is correct.
3. (Day 2) Move to separate tables and match the molecules built to the list found in your conclusion section.
Data and Observations: (Complete the following)
Draw the structural formulas for the two molecules built from your box:
Structure 1:
Structure 2:
Conclusions: Place the number of the model that correctly matches the name.
Hydrocarbons:
