Describe the appearance of your gas chromatogram; was there just one peak, or multiple peaks? If more than one peak was present, why do you think that is? 2. Compare your gas chromatogram with those collected for the different types of fruit. What peaks do these different citrus fruits have in common? What are the differences? 3. Look at the collected online data for your lab section and the entire class. For your section, what is the average amount of limonene for each fruit based on your classmates’ calculations? Is the amount of limonene consistent for each type of fruit? List some experimental reasons why the amounts may not be consistent. 4. Go online or to the Chemistry Library (see the Introduction/Table of Physical Constants for information on sources of chemical information) and look up the solubility of limonene in different solvents. Would water be a good solvent to extract limonene from citrus peels? Why or why not?
