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 1 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

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 the day of an excused absence must be turned in to your lab instructor by or before the beginning of your next regularly scheduled lab period If an absence is unexcused the lab report that was due the day of the absence will have 10pts deducted per day late Any student who knows about an excused absence in advance must meet with Dr Hubbard at least one week prior to the event to discuss their options If a student is going to be absent due to an event circumstance that is known in advance they must make arrangements to turn in their lab report on the original day that it is due In the
