Lab Schedule

Date	Activity
May 19	Monday Check In
May 20	Tuesday Lewis Structures handout will be distributed in lab. Due: Hand in Lewis Structures worksheet before leaving lab.
May 22	Thursday Recrystallization of Benzoic Acid is available here. Remember to save your benzoic acid so that you can determine its melting point in a future lab meeting.
May 27	Tuesday Isolating Natural Products (Caffeine): Liquid-liquid extraction is available here. Remember to save your crude caffeine so that you can purify it next lab.
May 29	Thursday Determine the melting point of your benzoic acid and sublime your caffeine
June 3	Tuesday Co-Distillation: The isolation of eugenol from cloves is available here. Remember to save your clove oil for analysis next lab. Due: Hand in your report for the Recrystallization of Benzoic Acid activity. Due: Hand in your report for the Isolating Natural Products (Caffeine): Liquid-liquid extraction activity.
June 5	Thursday An Introduction to the Gas Chromatograph: Collecting a chromatogram of clove oil is available here
June 10	Tuesday Regioselectivity: Electrophilic addition and bromohydrin formation is available here. We will synthesize the bromohydrin this lab and perform chemical tests on it next lab. Additional information about the lab is available here. The page contains videos and a flow chart that will help you understand the procedures followed during the experiment. The videos also show how the apparatuses used in the activity are set up. Due: Hand in the report for An Introduction to the Gas Chromatograph: Collecting a chromatogram of clove oil
June 12	Thursday Finish Regioselectivity: Electrophilic addition and bromohydrin formation AND start Stereospecificity: Electrophilic addition and bromohydrin formation, which is available here. Additional information about the lab is available here. The page contains videos and a flow chart that will help you understand the procedures followed during the experiment. The videos also show how the apparatuses used in the activity are set up.
June 17	Tuesday Finish Stereospecificity: Electrophilic addition and bromohydrin formation Due: Regioselectivity: Electrophilic addition and bromohydrin formation report.
June 19	Thursday Nucleophilic Substitution: Nucleophilicity and mechanistic effects can be downloaded from here. Due: Stereospecificity: Electrophilic addition and bromohydrin formation report.
June 24	Tuesday Alkene Formation: Dehydrohalogenation of 1- and 2-bromobutane and dehydration of 1- and 2-butanol is available here. Here is a web page with additional information about the dehydration and dehydrohalogenation activity. The page contains videos that will help you understand the procedures followed during the experiment and how the apparatuses used in the activity are set up.
June 26	Thursday Check Out Due: Nucleophilic Substitution: Nucleophilicity and mechanistic effects report. Due: Alkene Formation: Dehydrohalogenation of 1- and 2-bromobutane and dehydration of 1- and 2-butanol report.

PLEASE NOTE: Preparing a pre-lab (writing down the goal of the activity in the reaction section, looking up the properties and hazards associated with the chemicals being used and writing them down in the materials section, and writing down a plan/procedure that will be followed in lab) in your notebook before coming to lab is an important process that will help you complete the laboratory activities succesfully; thus, write-ups may be checked at the beginning of the laboratory period.

The faculty teaching this course reserve the right to unilaterally alter the schedule as needed. Any changes to the schedule will be announced in class and recorded in this document.
