Fresno State, Fall 2018
Welcome to CHEM 129A, Organic Chemistry Laboratory! This course will introduce you to one of the richest and most beautiful areas of modern chemistry: chemistry of carbon compounds. In CHEM 129A, we will learn skills that are essential for performing experiments in organic chemistry laboratory.
Read the syllabus carefully. Almost all questions about the course that you might ask can be answered by referencing the syllabus. If you are uncertain that you understand all rules and regulations, please contact me. Also, the syllabus for my sections differs slightly from those used in other sections.
The syllabus is a live document which is regularly updated. This syllabus and schedule are subject to change in the event of extenuating circumstances. If you are absent from class, it is your responsibility to check on announcements made while you were absent. Changes and corrections are listed in the changelog below and will be announced on Blackboard.
I will be available for in-office consultations Fridays 2–4 pm. Walk-in visits are welcome but appointments get first priority. If Friday doesn’t fit your schedule, there are additional time slots throughout the week available for appointments. To sign up for an office hours appointment go to https://muchalski.page.link/book

CHEM 129A is a two unit introductory laboratory course in organic chemistry. It is primarily concerned with introducing the tools and techniques that chemists use to synthesize and investigate the properties of organic compounds (see the list below). Some of these techniques are the same or similar to those you learned in general chemistry courses but may be modified because the experiments use very small amounts of material (microscale techniques).
Students who successfully complete CHEM 129A generally enroll in CHEM 129B, which further develops students’ laboratory skills. Some students then continue with CHEM 190, undergraduate research or independent study.
Students who successfully complete CHEM 129A should be able to:
Two 170-minute meetings per week (Monday and Wednesday) where we experimentally explore selected organic chemistry concepts (5.67 hours per week). Attendance is mandatory because you must complete all experiments to obtain a passing grade. Typically, the in-lab session will start with a short review of relevant material, concepts, and chemical safety through group discussions and problem-solving activities.
You will not be allowed to enter the lab if:
If you can not attend a lab meeting you must notify your instructor before the lab period begins. If you encounter and document a true emergency, I will make reasonable arrangements for you to make-up the lab and complete the assigned work. If the above conditions are not met, then a grade of 0 will be given for the missed lab.
I expect that you will come to lab with a basic understanding of the concepts that will allow you to fully participate in pre-lab discussions. Preparing for the lab means making honest effort to learn on your own by:
Out-of-class work also includes analysis of data collected in the lab. For the first half of the semester this will take form of post-lab summary written in your notebook. Later in the semester the post-lab analysis will include a typewritten lab report. (8–12 hours per week)
There are four kinds of graded work you will encounter in this course:
I will provide a template paper for you to write your notes. No need to buy additional notebook. You will submit your notebook pages electronically. At the end of each experiment set I will grade them and give you feedback.
Pre-lab notes contain answers to questions as well as documentation related to the planned experiment which you will prepare before carrying out scheduled experiments. In-lab notes document what you did in the lab (including notes taken during discussions) as well as results of your experimental work.
Assume that you’re in note-taking mode at all time when you’re in the lab. Well prepared pre-lab and in-lab notes are very important because they are the basis for the post-lab summary or report that you will write for each set of experiments. To know what to write and not to write in the notebook is a balancing act of relevance and brevity. You need only details that are relevant and necessary to reproduce the experiment. You can assume that your notes are going to be read by a trained organic chemist. For example, you don’t have to explain what is a round-bottomed flask.
Instructions for maintaining your laboratory notebook are in the textbook and will be discussed in the lab. Include all printouts (IR and NMR spectra, gas chromatograms, etc.) and sketches of TLC plates as part of you notes portfolio.
Your lab notebook is subject to evaluation at any time and must be kept current.
One of the main objectives of this course is for you to learn to interpret and communicate the meaning of experimental results. The post-lab summary or lab report is an assignment that shows the depth of your understanding of the concepts, techniques, and instrumentation used in the lab.
For experiments in the first half of the semester you will write a short summary of results and conclusions in your notebook. Later in the semester, a typewritten report will be assigned as post-lab summary and reflection. There will be total of six (6) typewritten reports. Four reports on scheduled experiments and two on results of practicals (see the schedule for details).
To grade the typewritten reports I will use a grading system of revision of your work that gives you multiple attempts to demonstrate the level of learning you achieved. Lab reports will be evaluated using a rubric that classifies the work with marks of Satisfactory (S) Progressing (P), or Incomplete (I). Points are not involved in grading reports. Work marked as Satisfactory will receive full credit. Reports marked as Incomplete or Progressing can be revised and resubmitted before the grade becomes final. If a resubmitted report meets criteria for Satisfactory grade, full credit will be awarded. Deadlines and conditions for submission of revised reports will be communicated via Blackboard.
Quizzes test your understanding of the lab techniques and experiments you conducted and will be based on material covered in the pre-lab lectures, reading assignments, and experiments. Quizzes will be take-home assignments because they test higher order thinking skills which are rarely well performed under the pressure of time. The only quiz we will have in class is the Safety Quiz.
Safety Quiz. You must pass the Safety Quiz to remain in the class. You can take the quiz up to 3 times. The quiz is based upon the information on safety sheet, your instructor’s lab lecture on safety, and Technique 1 (Safety) in the lab textbook. You are strongly encouraged to read the safety related notes, abide by the guidelines ALL THE TIME to keep the lab, lab occupants, and everyone else in the department safe.
These are the last two experiments for the semester (see Lab Schedule). You will be given a procedure (handout) at the beginning of the Practical session and your grade for these Practicals will be based on your skills and performance in the lab (yield and purity of your product) and your experimental write-up.
Grade brackets are imposed by course coordinator. In the past, the grading scale followed a pattern close to the following: A = 85–100, B 75–84, C 65–74; D 50–64; and F <50.

I want you to be successful in this course. I will do my utmost to help you do this, by creating and maintaining a learning environment based on challenge and support and giving my highest professional commitment to your success and well-being. But, I cannot achieve success for you. Success in college courses comes from cooperation with instructors, interaction with your classmates, and diligent effort throughout the semester. I like to compare successful classroom interactions to interactions between players and coaches on a sports team. Players do the work and coaches make sure players do the work that helps players succeed.
My primary responsibility is to create a learning environment where it’s safe to take risks and make mistakes, without shaming or judgment, and to give you feedback and guidance as you grow in your understanding of the subject. As my students, you have a right to expect from me:
If you perceive that I am falling short in any of these expectations, you have the right and responsibility to give constructive feedback that helps me improve. I will consider all reasonable suggestions in the course regarding my instruction or the course design.
Copies of lab notebook pages are submitted electronically. It is the student’s responsibility to make sure these items are submitted on time, through any means necessary, even if technology issues arise. If a tech issue arises that prevents your being able to submit work on time, it is your responsibility to find another way to get it to me (for example, via an email attachment). Technology issues that are avoidable or resolved with a simple work-around will not be considered valid grounds for a deadline extension. For example, if you are trying to upload a Lab to Blackboard and Blackboard won’t accept the file, you should try again later or send the file as an email attachment until you can upload it successfully.
For most other assignments you are allowed and encouraged to work with others. However, the final product that you submit for feedback must be the result of your own efforts. Therefore you may share ideas and strategies with others, but collaboration on the actual finished product you submit is not allowed. Your work is expected to be the product of your own thinking, written and explained in your own words with no parts of the work copied from external sources such as books or websites, and done clearly enough in your own mind that you could explain the work from start to finish if asked. Specifically, this excludes:
Violation of this policy is considered “academic dishonesty” and carries with it strong punitive measures mandated by Fresno State, including possible automatic failure of the course or suspension from the university. For details, please see APM 235 by going to http://www.fresnostate.edu/aps/documents/apm/235.pdf.
You may feel tempted to academic dishonesty at some point in the semester. The work can be difficult, and many of you are under a lot of stress. If you are considering academic dishonesty, please STOP, take a breath, and remember that your classmates and I want you to succeed in the course. You are not alone, and you have a strong network in the class for getting help. The revision and resubmission policies mean that it’s OK to turn in work that isn’t perfect. There is no need to be academically dishonest! Just do your best on the work, and you’ll have the chance to revise it later.
Students may drop classes using the on-line system through Thursday, September 13. The Drop/Withdrawal Form, signed by instructor and department chair, is needed to drop a course after that date. Withdrawals processed before 9/20 will not show on the official transcript. Serious and compelling drop period begins on September 21 and ends on November 20. More details on Admissions web pages
A serious and compelling reason is defined as an unexpected condition that is not present prior to enrollment in the course that unexpectedly arises and interferes with a student’s ability to attend class meetings and/or complete course requirements. The reason must be acceptable to and verified by the instructor of record and the department chair. The condition must be stated in writing on the appropriate form. The student must provide documentation that substantiates the condition.
Failing or performing poorly in a class is not an acceptable “serious and compelling reason” within the University policy, nor is dissatisfaction with the subject matter, class or instructor.
In addition to course policies, you are expected to be familiar with Academic Regulations described in the http://www.fresnostate.edu/catalog/academic-regulations/ as well as policies listed below.
Policy on Cheating and Plagiarism
Students with Dissabilities
Policy on Disruptive Classroom Behavior
Lab reports assignments are graded either Satisfactory (S), Progressing (P), or Incomplete (I). The base criteria for all reports are as follows (some reports may have additional criteria which will be explained withing the assignment):
