Organic Chemistry:
-Define what organic chemistry is
(the study of carbon compounds)
-What are the two factors that determine the properties of organic compounds?
(the skeleton formed by the carbons and the functional groups H’s, and OH’s or C’s that branch off of the carbon “skeleton”)
-Know the first ten compounds of the simplest alkanes
(1- methane, 2- ethane, 3- propane, 4-butane, 5- pentane, 6- hexane, 7- heptane, 8- octane, 9- nonane, 10- decane)

(see assignment that was done in class)
Hints:
-Manage your time (3 hours to write)
-Look at the points each question is worth (prioritize and for detail)
-If you don’t know something, skip it and come back
-Check over the entire exam after you are finished if there is time (not just skimming it)
-Rest (do not stay up studying the night before until late)
-Ask if unsure while writing the exam
-Review everything before Monday, June 18th (review day) so that you can come in and ask questions
