Course Requirements

A more succinct and logical version of this syllabus can be found at:

Emphasis is placed on techniques, properties and reactions, and reinforcing principles offered in the lecture portion of the course.

Prerequisites: CHEM 1412 or equivalent.

Corequisistes: CHEM 2323 and CHEM 2123 must be taken simultaneously

"Operational Organic Chemistry: A Problem-Solving Approach to the Laboratory Course", 4th, Lehman (red cover). This is the book you must use. An older edition is not acceptable.

You will need a scientific calculator for lab activities only.


Incomplete Grade Policy: Incompletes can be given if you complete 75% of the course work with at least a 70% average. 

Withdrawal Policy: If you wish to drop the class, please do so yourself, the instructor will not be responsible, unless you make a specific request prior to the drop deadline. The drop deadline is November 18, 2010

Grading: Graded materials consist of a lab quiz (20 points), the lab report (65 points) and technique /yield (15 points). Lab reports will be turned in the week following completion of the experiment, at the beginning of lab. Lab reports more than one week late will not be accepted.

All students perform their own experiments. There will be no lab partners unless directed otherwise by the instructor.

ACC does not provide safety goggles for the lab. The student must buy goggles prior to performing the first experiment. ANSI-approved goggles are stamped with Z87.


Lab Report Format – General Information: Labs may be written on regular notebook paper, in a lab book with carbon/carbonless copies, or they may be computer-generated. Legibility is important. You do not want to use a notebook (e.g., composition book) that does not have removable pages, as labs are turned in on a weekly basis.

Plagiarism: From the Student Handbook: “Academic work submitted by students shall be the result of their own thought, research or self-expression.” “When students borrow ideas, wording or organization from another source, they shall reference that information in an appropriate manner.”

Plagiarism in lab reports will result in a zero for the lab that will be automatically factored into the lab grade.

Lab report contents:
Title - Name of experiment, and experiment number from lab book.
Pre-lab - Questions to be answered prior to lab.
Objective - Concise (1-2 sentence) statement of the goal of the experiment.
Discussion - This is about 1-3 paragraphs (2 page, maximum) in length. It may include the theory behind laboratory techniques and the chemistry (reactions, mechanisms, formulas, structures, etc.) written in the student's own words.
Procedure* - A numerical outline of each step you will perform in the lab. Notation of all changes will be made here. Also include calculations of volume/mass of reagents needed and the theoretical yield.
Data and Observations* - All numerical data and other observations such as color, odor, and comparisons to other classmates’ experiments, and deviations from written procedure.
Results and Conclusions - Statement (2 paragraphs) stating the results and discussing your interpretation of the results, sources of error, what was learned, etc.
Follow-up Questions - Questions to be answered upon completion of the lab.

 *Note: It is most convenient to combine the procedures, and data/observations onto the same page. Draw a vertical line about two-thirds of the way to the right on the page. Write the procedure on the left side. The right side is available for data/observations associated with each step in the procedure.

Preparation before coming to lab
Prior to attending lab, you must complete the lab report from the Title up through the Procedure. If these materials are incomplete, you may be dismissed from the day's experiment, with no chance of make up. If you miss a lab, you may miss some discussion/handouts about the next period’s experiment. You are responsible for getting this information from the instructor or another student before the next lab.

Student Learning Outcomes/Learning Objectives

Students will be able to perform the following skills:

  • Read NFPA, HMIS labels and understand the hazard of chemicals used.
  • Transfer sample to balance for weighing and tare the balance.
  • Measure temperature with a thermometer.
  • Correctly read a meniscus and accurately measure a liquid volume.
  • Correctly use hot plates and heating mantles.
  • Observe and interpret chemical reactions: color change, temperature change, precipitate formation, and gas evolution
  • Perform a gravity and vacuum filtration to separate liquids from solids
  • Separate mixtures of substances chromatographic techniques
  • Extract information and write experimental procedures from laboratory texts and supplemental material
