* Laboratory reports for these experiments are due on the period following the completion of the experiment (completion is noted by an asterisk). Note ­ The extraction experiment is three periods long, combined with recrystallization and melting points. The dehydration of 2-methylcyclohexanol and gas chromatography labs are combined. Late reports will only be accepted with prior permission from the instructor.

Ý For synthesis experiments, the "Balanced Reaction" and "Table of Reactants and Products" must be completed before you start the lab.
