Gas Chromatography - Analysis of an Alkyl Halide Product MixtureLab Grade [Main Sequence Labs - 2211L]:1 University of Georgia Modern Organic Chemistry I Laboratory CHEM 2211L Spring 2019 Lab Coordinator: Dr. Richard Hubbard Email: [email protected] (email will not be accepted via ELC) Phone: 542-1974 Office: Science Learning Center 119B Office Hours: Tuesday, Wednesday, Thursday 2:00 – 3:00 pm Lab Manual: CHEM 2211L Organic Chemistry I Laboratory Manual, Hubbard and Morrison (Hayden McNeil, Spring/Summer 2019 Edition only) Lab Notebook: lab manual includes a carbonless duplicating notebook. All data and observations will be written on the tear-out sheets provided in the lab manual. Safety Equipment: Lab safety goggles (mandatory), Lab coat (mandatory) General Info: Each week you will report directly to your assigned laboratory (rooms 101, 102, 105, 106, 125, 126) for a pre-lab quiz and lecture given by your laboratory instructor. After the pre-lab lecture, you will begin your experimental work for the day. Lab Check-In: During your first lab meeting you will be checking into the communal lab drawer(s) that you will be using each week throughout the semester. It is imperative that your drawer(s) be fully equipped and organized following each lab experiment during the semester. If your drawer is missing any equipment during check-in, you will need to visit the lab manager in the chemistry stock room (room 111) to replenish your supplies. Once you are satisfied that your drawer(s) are appropriately stocked, sign your lab safety contact and turn it in to your TA. Your lab check-in will then be complete. From that point forward, you and your partner will be held solely responsible for the condition of the glassware in your lab drawers following each experiment. At the end of each lab period, your TA will check you out of your drawer(s), making sure that all of your glassware is present and accounted for. If any of your glassware is broken or misplaced during the course of the semester, you and your partner are required to replace it in a timely manner. A record of all broken/misplaced glassware will be kept by the lab manager. If an item is broken/misplaced, it is up to you and your partner to obtain a temporary replacement item from the lab manager in the glassware room. You will then have one week to bring a permanent replacement item to the lab manager. A complete glassware list is provided at the end of this syllabus.2 Experiments: The experiments in CHEM 2212L focus on teaching basic/essential organic laboratory techniques, in addition to exposing you to some of the commonly used analytical instruments. You will be working with a lab partner this semester, but your collaboration will only extend to your in-lab experiments. All labs write-ups are to be done independently. The following is a list of the techniques, instrumentation and support software that you will be introduced to this semester: Laboratory Techniques: Recrystallization Melting Point Determination (Simple/Mixed) Boiling Point Determination (Microscale) Distillation (Simple/Fractional) Extraction (Solid/Liquid, Liquid/Liquid, Acid/Base) Reflux Filtration (Gravity/Suction) Thin Layer Chromatography Instrumentation: Gas Chromatography (GC) Infrared Spectroscopy (IR) Nuclear Magnetic Resonance Spectroscopy (NMR) Computer Programs: ChemDraw ChemDraw 3D3 Chemistry 2211L Schedule of Experiments Spring 2019 Week Of Experiment January 14 Check-In, Safety Lecture January 21 MLK Day [No Labs] January 28 1.

Retro and Forward Diels-Alder Reaction April 15 Lab Check-Out April 17 Final Exam 7:00-8:00 pm4 Lab Reports: Lab reports are due at the beginning of lab each week and will be graded and returned to you the following week. If your lab reports are not being returned to you in a timely manner, arrange to meet with Dr. Hubbard as soon as possible so that the situation can be corrected. A set of general guidelines for writing proper organic lab reports is provided for you in this manual. Refer to the section entitled “How to write a lab report.” Your TA will supplement this information with more specific details at the beginning of the semester. Make sure that your writing style and report layout carefully adheres to your individual TA’s specific writing parameters. Each report must be submitted with a cover sheet. A copy of the cover sheet is provided at the end of your course syllabus on ELC. Each student must submit their own, individual lab report. You are expected to work independently. Plagiarism, in any form, will not be tolerated. If you are unclear as to what constitutes plagiarism, the following website is a valuable resource for information: Plagarism.org: http://www.plagiarism.org/ Absences: In order for an absence to be considered excused, all appropriate documentation must be presented to Dr. Hubbard. You have one week to turn in your documentation to Dr. Hubbard or your absence will be considered unexcused. You may not turn in your excused absence documentation to your TA. • Any missed experiments will be counted as a zero unless an excused experiment approval form is obtained from Dr. Hubbard. • Any student with two or more excused absences will be assigned a grade of incomplete ("I") for the course. The student then has three semesters to complete their missed assignments in order to obtain a grade for the class. If the work is not completed by the end of the third semester, the incomplete will automatically change to an F. • Any lab report due on
