Chemistry 313
Organic Laboratory I
This laboratory course is Web CT-based
Instructor: Dr. Maher Mualla
Text: Macroscale and Microscale Organic Experiments by K. L. Williamson; Third Edition, Houghton Mifflin Company, 1999.
Course Objectives:
This laboratory course has three objectives:
1. To develop familiarity with equipment and techniques that being used in
chemical laboratories.
2. To learn the process of scientific inquiry (observing, measuring, recording,
and interpreting data).
3. To apply the acquired knowledge to identify and solve problems.
Pre-laboratory Preparation:
Students are expected to prepare for the lab by completing the following two
steps:
1. Read and comprehend the assigned readings and procedures (see below) for
the experiments we will be carrying out in the lab that week.
2. Write in your notebook the names, structures, physical properties (ex.
Liquid, bp 123-124 or solid, mp 75-75.5) and the hazard nature (ex. Poison
or Flammable) of each chemical you will be using in the lab. These data can
be obtained from the Aldrich catalog available in the lab or on reserve in
the library.
Laboratory Reports:
A well-written laboratory report is required for each experiment. For experiments
that include unknowns, the lab report is for the unknown only. The report
should be submitted on-line (Web CT).
Attendance Policy:
Attendance is required. Missing THREE laboratory periods will result in an
F grade in the course.
Grading Scale:
Lab Reports 70%
Final Exam 20%
Attendance and Evaluation 10%
