On scheduledlecture and exam days you should come to room 320 at 2:00 PM. All other class days you shouldgo to the lab (room 301, 303, 336 or 340) directly. Regular attendance and being present on timefor lectures, exams and lab work is required.Each section will have its own teaching assistant. The faculty supervisor for this courseis Dr. A. Cammers. His office is room 349 (phone: 323-8977; e-mail: [email protected]). He can be reached by scheduling an appointment. The laboratory supervisor for all sections isDr. M. A. Patwardhan. Her office is room 327 (phone: 257-3659; e-mail: [email protected]). She can be reached in that vicinity Mondays and Wednesdays from noon to 3:00 PM, andTuesdays, Thursdays from 8:00 AM to 3:00 PM, or you may schedule an appointment. You will be given handouts for this class during the semester. You may also usecomputer program ‘Identification of Organic Compounds’ (IOC), available at network computersin Chemistry / Physics Building and W. T. Young Library. You must purchase the required(Hayden-McNeil) student laboratory notebook.GRADINGYour final grade will be calculated based on the following:IOC assignments 5%Exams (2) 20%Lab reports (10)Singles (3) 18%Separations (3) 18%Identification of separated compounds (4) 24%Final examination 15%Letter grades will be assigned using the following scale:A 90-100%B 80-89%C 70-79%D 60-69%E # 59%SAFETY AND RESPONSIBILITYFailure to observe safety rules and / or failing to behave in a safe and responsible mannermay result in a failing grade and permanent dismissal from the course.CHEATING AND PLAGIARISMThe Department of Chemistry considers cheating a very serious offense. The minimumpenalty for cheating or plagiarism is the assignment of a grade of E for the course, in accord withUniversity Senate Rules. Attempts to claim another person's work as your own, in any form orunder any guise, is forbidden. All the work that you do for this course, must be your own only.This includes, lab write-ups, reports, data, spectra, results, laboratory notebooks, exams, etc.Falsifying laboratory data or ‘dry labbing’, making up data is cheating.2Removing laboratory chemicals, reagents or any other items from the laboratory isforbidden. Such behavior may result in a failing grade and permanent dismissal from the course.LABORATORY NOTEBOOK, DUE DATES AND MAKE-UP POLICYYou must be present in the lab, on time. On the days, when a lecture or an exam isscheduled, lab work will start immediately following the lecture or the exam. On all other days itwill start at 2:00 PM.During each laboratory period, all the data and comments must be entered in yourduplicating notebook. Your notebook must be given to your teaching assistant to inspect andinitial. The duplicate (copy) sheets with all information must be turned in to your teachingassistant before you leave. All your other data such as IR spectra, GC printouts etc. must have your name and datewhen you recorded it. Before you leave, you must have your TA sign and date it. There will be apenalty for failure to do so. For the details about the departmental laboratory notebook policy,refer to:http://www.chem.uky.edu/courses/common/notebook.htmlDue dates for turning in lab reports are given along with the schedule. All the lab reportsare due at the beginning of those lab days. Ask your teaching assistant for the details of how towrite laboratory reports. The teaching assistant for your section will grade all your work,including all the exams. There will be a penalty for turning in lab reports late. If you have any questions regarding grading of any assignment, you must contact yourTeaching Assistant or Dr. Patwardhan within one week of the date on which the assignment wasreturned. We reserve the right to regrade the whole assignment. Any assignments returned forregrading after more than one week from the day the assignment was returned will not beconsidered for regrading.On the days when exams are scheduled, you must be in the classroom by 2:00 PM. Youmust take assigned seats based on the seating chart. You must not leave the classroom until 2:10PM, even if you finish the exam. You will not be allowed to take the exam if you arrive after2:10 PM. Fifty-minutes are allowed for both exams. Students who miss scheduled class or exam for an excused absence, please contact Dr.Patwardhan as soon as possible. If an exam is missed without an excused absence, a '0' will berecorded as the grade for that exam. If students with an excused absence can not take the missedexam within one week of the original exam time, their final exam will count proportionatelymore. The manual Student Rights and Responsibility describes what are excused absences.UNKNOWNS AND SEPARATIONYou will be given three single unknowns. You will identify each single unknown. Foreach single unknown, you will perform several tests such as preliminary tests, solubility tests,recording of melting or boiling point, recording of Infra red spectrum, at least three classificationtests, etc. which will help you in identifying the unknown. For each single unknown you willwrite up a lab report explaining both the experimental work and logic you used to identify theunknown. For any of these three unknowns, you may also prepare a solid derivative. Ask yourTA to give you the procedure for preparation of derivative.You will be given three unknown mixtures containing two compounds each. You willseparate all three of these to get six pure compounds. The expected purity of each of theseparated compounds should be 95% or more. After the separation, you will write up a lab reportexplaining the experimental work, proof of purity (as evident by melting and or boiling points,infra red spectra, GC data, TLC data etc.) and the logic used for separation.3You will continue to identify any four, of these six compounds, obtained afterseparations. You will write up lab reports explaining both the experimental work and logic youused to identify these. Additional credit will be given for identifying and writing lab reports formore than four compounds.You may use up to two mass spectra to help you in any of these identifications. You will be writing a minimum of ten lab reports.Identification of Organic Compounds (IOC)You will obtain
