BINGHAMTON UNIVERSITY STATE UNIVERSITY OF NEW YORK CHEMISTRY 335 - COURSE INFORMATION FALL 2020 revision of 08/23/2020

Note: additional course information and guidelines are in the lab manual Laboratories: As Arranged, SC-II, Rooms 206,207, 210 Office Hours: Office hours and locations to be posted. Description: This is a laboratory course for introductory organic chemistry. General Introduction The Chemistry 335 laboratory provides an opportunity for students to have an individual "hands-on" experience in basic organic techniques, organic synthesis and selected instrumental methods of analysis. Laboratory skills will be developed in early exercises and then applied more specifically in later experiments. Since each class has students with wide differences in previous laboratory experience and individuals that differ widely in manual dexterity, the degree of improvement in laboratory skills and the development of selfreliance are emphasized. The objectives of the laboratory program will provide students with enough experience to: 1) Work safely and comfortably in a laboratory 2) Carry out basic laboratory techniques and modern instrumental methods 3) Make careful qualitative observations and to obtain acceptable quantitative data 4) Keep a complete, accurate and well-organized record of experimental lab work 5) Evaluate experimental and instrumental data 6) Write valid conclusions based on the evaluation of recorded data

Grading Procedure: The final grade in CHEM 335 will be derived from laboratory work, from prelab homework exercises posted on an online system, and from two exams given during the semester. Individual laboratory exercises will be graded during the semester BY A POINT SYSTEM. All laboratory exercises must be completed in order to receive a passing grade in the course. The term exams during the semester will cover the fundamental principles underlying the laboratory experiments. The course grade will be based on a numerical average in which the laboratory exercises will count 50%, the two term exams count 30%, and prelab homework assignments will count 20%. Homework assignments will be done using the LON-CAPA system. 1

Laboratory Safety: Chemical Splash Goggles and knee length lab coat are required at all times in the chemistry laboratory. These can be purchased at the University Bookstore. Persons engaging in unsafe practices while in the laboratory will be asked to leave and will receive a failing grade for that session. Late arrivers to the lab will generally not be allowed to enter.

GENERAL COURSE GUIDELINES 1.

Missed laboratory periods may be made up only with permission of the instructor, and during regularly scheduled make-up periods. Documentation of the reason for missed sessions is required for approval of make-ups. You may not work in other laboratory sections without approval of all instructors.

2.

The final course grade is determined by a combination of lab scores, exam scores, and homework (loncapa) scores. At the end of the semester, each of these three components will be converted to a percentage, and combined in a 50:30:20 ratio of labs:exams:homework. Final grades of 90% or above fall in the A-/A range, 80% to 89% in the B-/B/B+ range, etc.

3.

The laboratory component of your final course grade is based on laboratory reports that you will submit biweekly, after completing the corresponding lab exercise. There will generally be a point deduction for late submission of lab reports, and reports submitted more than one week after the due date will receive no more than half credit. Lab reports are submitted electronically through the university blackboard site.

4.

Examinations are cumulative. They build on material that has been taught earlier in the course, and may contain questions on earlier material. Ordinarily, most of a later examination will concentrate on material that has not already been covered by an earlier examination. Exams will contain questions based on laboratory material as well as lecture material. A single, comprehensive, make-up exam will be scheduled during final exam week for students who miss one of the two term exams for a valid reason.

5.

All written work (such as lab books, examinations and quizzes) turned in for credit becomes the property of the university and the instructor. Ordinarily this work will be graded and returned to the student for review. The body of graded work, completed within the time limits of the course, as well as classroom and laboratory participation, serves as the basis of the final grade. Apparent lack of preparation for lab, or unsafe laboratory behavior, such as horseplay, can, and probably will, result in an UNSATISFACTORY grade for a lab.

6.

Material will be considered for a re-grade, as long as it is submitted no later than one week after the work has been returned to the class. Attach a piece of paper to the work at issue, or email the instructor, briefly describing what you see as the problem, and how you believe it should be changed.

7.

For many of the experiments you perform in the lab, you may be working with a lab partner. It is expected that you will be working with a partner only while performing the actual experiment and collecting any needed data. At the end of the lab period, you should have all needed data recorded in your notebook, and no further collaboration with a lab partner should be needed while writing up your final lab report. You should also expect not to be working with the same lab partner for the entire semester. Lab partners will be assigned by course TA’s on a rotating basis.

8.

Academic dishonesty of any kind is taken seriously by the Chemistry staff, and, if detected, is prosecuted to the full extent of the available university sanctions. We all recognize that collaborative study and consultation is an important adjunct to individual learning, and is to be encouraged. However, once these positive collaborations have occurred, construct your own individual laboratory pre-lab preparations and final reports. Consult examples of laboratory reports from previous semesters that have been successful, but avoid copying them directly. Avoid possible misunderstandings arising from work submitted for regrade by making notations on the questioned portions in contrasting pen or pencil.

9.

Electronic Device Policy. Cell and smart phones, MP3 players, tablets/laptops and other similar devices must be turned off or muted before entering the laboratory or discussion rooms. Students using any of these devices during lecture may be asked to leave the room. Students using any of these devices during a laboratory exercise, without the instructor’s approval, will receive a failing grade for that lab report. If you anticipate or receive an emergency call on your phone during laboratory or recitation session, please notify the instructor.

10.

Academic Disruptions: In the event of an extended academic disruption which prevents students from physically attending a lab session, distance learning assignments will be provided through an online homework system. Students will be asked to solve a problem similar to what would have been scheduled in the lab they missed. They will be provided supplemental material as needed, and ask to analyze hypothetical results. They will submit a report discussing how the lab experiment would have actually been performed, along with an analysis of the hypothetical results. Online materials, such as power point presentations, or video recordings will be posted to help students as needed. Students will be expected to attend online group help sessions scheduled during their regular class meeting times.

11.

Finally, and most importantly, we take the issues of safety in the laboratory very seriously. Be sure to wear eye safety goggles and lab coats at all times in the laboratory, and observe all other laboratory safety precautions, some of which may be specific to individual experiments. Violation of ordinary safety procedures, such as eye protection, is certain to lead to a failing grade being recorded for that experiment, even if not to personal injury because of accident. While a chemical laboratory can be a dangerous place for the unthinking and unprotected, we can all assure ourselves of a safe working and learning laboratory by having sensible precautions carefully followed. Over many years we have had few injuries, and, with your cooperation, we will have many more years with even fewer incidents.

FALL 2020 TERM & CORONAVIRUS CONCERNS Chem335 – Organic Chemistry Laboratory – is a laboratory science course. Upper level laboratory science courses are meant to provide a hands-on learn by doing experience. It is hoped that all students will physically attend most of the lab sessions this term. There is no online, or “distance learning” option, can provide the same learning experience as physically going into the lab and trying to make an experiment work. Nonetheless, it is likely that the course will need to be modified this term, and that remote learning alternatives will be needed, as covid-19 concerns remain. Physical Distancing: For this term, we will be unable to run a typical four-hour lab session for each of our lab exercises, with a full class of sixteen students per lab section in attendance. Physical/social distancing rules that need to be observed will prevent having the lab rooms filled to capacity. The options being considered involve splitting a lab section of sixteen students into smaller groups, perhaps two groups of eight each, and using remote learning modules as needed to supplement actual physical attendance in the lab. With each lab section split into two groups (A and B), the options being considered are 

To reduce crowding in the lab during the current semester, a reduced number of actual experiments will be physically completed in the lab, on a biweekly schedule, complemented by distance learning modules to be completed by all students. Groups A and B physically rotate weekly; one group attends the lab to do an actual hands-on experiment, while the other group will be expected to attend remote sessions and work on remote learning modules.



Split the four-hour lab into two 2-hour sessions. Group A physically attends the first two hours, then group B the second two hours. Each group thus has a chance to see their TA discuss and demonstrate how the lab experiment would work, and perhaps complete part, if not all, of the actual lab exercise. Alternate data and results could be used as supplements to a shortened lab exercise, and lab reports completed using alternate results as needed.



There may come a point in time when all lab exercises must convert to a “distance learning” format. In this case, everybody will work on fully remote lab modules to complete the semester.

It is likely that we will have to adjust our approach to handling the course as the semester progresses. Students should closely monitor blackboard and e-mail messages to stay up to date as we proceed through a semester of great uncertainty.

Learning Environment Online Environment: All videos and recordings posted for this course are for academic purposes only and should NOT be shared in any way. If you are caught misusing or sharing course videos or recordings for any purpose, the incident will be reported to the Office of Student Conduct. Maintaining a Safe and Healthy Environment: Binghamton University has adopted requirements to protect the health of students, faculty, staff, and the community at large. Safeguarding public health depends on each of us strictly following these requirements. As a condition of enrollment, each student has acknowledged a statement of Rights and Responsibilities for the semester; included in this document is an acknowledgement that all campus requirements for spacing and wearing face coverings must be followed at all times. Health and safety standards will be enforced in this course. The academic and course-removal sanctions listed here are provided because the Provost’s office considers them to be valid responses if a student puts the safety of others at risk. Non-compliance with face covering and/or spacing requirements, or attempts to attend class for the Student Rotation Model courses when not scheduled to do so, constitute a serious public health risk and a disruption of the learning experience. In accordance with such rules, eating and drinking are prohibited in the classroom because they would require the removal of the face covering. For in-person courses, current rules require everyone to wear a face covering correctly so that it completely covers both the nose and mouth tightly at all times in the classroom, and to maintain 6-foot spacing in classroom seating. A face shield is not an acceptable substitute. If you forget your face covering or it does not meet these requirements, you will be asked to leave the room immediately. You may not return until you meet the requirement. Students are required to be seated in a manner that meets the necessary spacing requirements; failure to comply with these requirements constitutes a public health risk to everyone in the learning environment and disrupts the class. If a student does not comply with the requirements and refuses to wear their face covering properly or to leave the classroom when directed, or to follow instructions for reseating when directed by the instructor, the instructor will immediately cancel the remainder of the class session and inform the dean’s office, which will work with the Student Records office to issue a failing grade (“F”) for the course regardless of when in the semester the incident occurs. The dean’s office will also inform the Office of Student Conduct. If a student’s refusal to comply is a second offence, the Office of Student Conduct may recommend dismissal from the University. If the rules for health and safety measures change, the campus will be notified and the new requirements will take effect. 8

If you become ill or are asked to go into quarantine/isolation, you are not allowed to attend class in person. You should immediately notify the instructor and plan to participate online if you are able to do so while following instructions from health providers and/or health authorities. Further information on COVID-19 symptoms and next steps are available here: Health. Students who exhibit symptoms should call the Decker Student Health Services Center at 607-777-2221 first
