Description:† This is a research project on a molecule that is related to your field of interest.† This project will have progressive due dates.† The report will become more in depth with each due date.† You may also revise any previous sections and turn them in with a later section.† The whole project is to be kept in a folder.† Write out each question in bold type just before each response.† Some responses to the questions may apply more to your molecule than to another molecule.† Therefore, you may have some responses that are much longer than others.
1. What is the molecular formula and molecular weight and percent composition of your molecule? (Show all calculations)
2. What are the different elements in your molecule and how many of each?
3. What are the different names of you molecule?† How many of each?
4. What are the chemical and physical properties?† How are these useful?
5. Is this molecule usually (room Temperature) a liquid , solid or gas?† Is it ever found in solution?† Why?
6. Give at least three different classes or groups that your molecule fits into.† Explain each.
7. Draw 5 different pictures/models of your molecule? (Electron dot, structural, ball and stick, or space filling).† Each diagram should be at least one page in size.† Either the ball and stick or space filling model must be from 3 different angles.
8. Who would use this molecule?† Why?
9. Draw a picture of the following organic groups or end groups (parts of organic molecules) benzenes, alcohols, esters, aldehydes, ketones, carboxylic acids, ethers, amines, and amides.† Which ones are part of your molecule?† How are the end groups that are in our molecule produced?
1. How does your molecule react?† What are some chemical reactions of your molecule?† Why does it react in this way?† How do the organic end groups that are in your molecule react?
2. What are the useful and harmful characteristics of your molecule?† Are there any products that contain your molecule?† Which?
3. How is it produced either in nature or in a factory?† Is it found in nature?† Why or why not?†††††††††
4. What role has your molecule played in history?† Who discovered it?
5. Is your molecule used to make other molecules?† Which ones?
6. Is your molecule ever part of a larger molecule?† Which?
7. How might a scientist identify this molecule?† Explain how infrared spectroscopy is used.† Discuss NMR spectroscopy and /or mass spectroscopy.† Find the actual spectrum.
8. Is your molecule found in nature or in useful products with another molecule?† Why is this mixture important?† How do the two or more molecules interact with each other?† How does this affect your molecule?
9. Donít forget to revise and improve part 1
1. Is your molecule polar or nonpolar?† Why do you conclude this way?† Does it form any intermolecular bonds?
2. What is it about the structure of your molecule that gives it its properties?
3. What are some molecules with similar properties?† Why do they have similar properties?
4. Describe the energy of the bonds and the roles the bonds play.† What is the energy of each bond?† What is the total energy (enthalpy) of formation of your molecule?† How is this energy of formation found or calculated?
5. What role do the elements play in determining the properties of the molecule?
6. What role do the electrons play?† How do the structure, shape, and elements of the molecule influence the electrons? How is this important to the function of the molecule?
7. What are the isomers of your molecule?† Do they have similar properties?
8. What are the effects of your molecule on the body?† (Good and bad)
9. What are the effects of your molecule or products of your molecule on the environment? (Good and bad)
10. What are the crystal structures of your molecule?† Draw them.
11. Calculate the electronegativity of each bond.† Are they polar, nonpolar, or ionic?
12. Donít forget to revise and improve parts 1 and 2
Organize your work into a portfolio.† Include all originals and revisions.† Make sure everything is well labeled.† You must include a bibliography of all of your sources.† You need to have at least 3 reference sources (CRC Handbook, Merk Manual etc.), 3 other book sources (Molecules by P.W. Atkins), 2 current magazine sources, and 5 web sources.† Include these sources in a numbered list that is noted throughout the portfolio.† At the front of the portfolio you are to include these questions and your responses:
1. What did you like best about the project?
2. What was the most interesting thing you learned about your pet molecule?
3. What did your pet molecule teach you about Chemistry?
4. What is one thing you wold like to know more about your pet molecule?
5. If you could do one experiment with your pet molecule, what would it be?
