B CUSP 242
Preparations and qualitative organic analysis. Designed to be taken with B CUSP 239. Prerequisite: minimum grade of 1.7 in B CUSP 238; minimum grade of 1.7 in B CUSP 239, which may be taken concurrently.
B CUSP 242 is the second of the two-quarter competency based organic chemistry lab sequence that will provide students with greater exposure at some instrumental and practical techniques of organic chemistry. The experiments during this quarter will provide opportunities for students to improve their skills at data acquisition as well as at interpreting data obtained from instruments including those of spectroscopy. An exposure to organic qualitative analyses which characterizes the tests and reactions of the various classes of organic compounds will also provided.
Prerequisite: Minimum grade of 1.7 in B CUSP 238 and B CUSP 241. Students concurrently enrolled in B CUSP 239 can take this course, unless they have completed B CUSP 239 with a grade of 1.7 or better.
Student learning goals
Understand and learn the theoretical principles of the experimental techniques or procedures. Answer all the theoretical and practical questions and solve numerical/mathematical problems that highlight the understanding of the experimental concepts and principles.
Make the connection between the objective/purpose and the experimental technique or procedure that the experiment represents. Come prepared to the lab period so as to perform the experiment confidently and with the safe execution of all the steps in its procedure. Throughout the duration of the lab period maintain a clean and a safe lab environment.
Continuously record experimental data and make notes of detailed observations while working in the lab. Maintain the lab notebook by developing good writing habits and constantly tabulizing data and observations in a manner that would lead to an easy replication of the experimental procedures.
By employing the skills learnt during B CUSP 241 along with developing any new skills, perform all the characteristic tests that would help determine and confirm the identity of an unknown organic compound (organic qualitative analyses).
Effectively communicate the experimental data, observations, and results to colleagues, and peers either orally or through the generation of experimental reports and/or datasheets. Critically evaluate the results obtained from any of the experiments.
Be able to answer questions and solve problems pertaining to the practice and theory of all experiments on any quizzes as well as on any practical and written exams that are administered.
General method of instruction
Successful completion of all the course experiments during the lab periods. Attendence is required at all the lab lectures where the procedures and techniques are demonstrated and discussed along with the detailed presentation of the theory of the experiment as well as the pertinent tests of organic qualitative analyses.
Successful completion of both B CUSP 238 and B CUSP 241 with a grade of 1.7 and better. Working collaboratively and independently in a lab setting. Acquiring lab data and maintaining a lab notebook with all the appropriate lab procedures and details.
Can be taken either concurrently with or after the successful completion (with a minimum 1.7 grade) of B CUSP 239.
Class assignments and grading
Lab work that involves a safe execution of the experimental techniques and procedures. Written pre-lab exercises, maintaining a proper lab notebook, and generating post-lab reports with appropriate conclusions along with the answers to any numerical/non-numerical questions. Correct identification of the unknown compounds of qualitative analyses.
Student evaluation will be based upon 1) the safe performance of the actual experiment during the lab period. 2) quality of the data and results procured from an experiment. 3) correct identification of the unknown organic compounds. 4) a practical lab exam conducted during the lab period that involves an individual performance of an experiment. 5) written exams over the course material that would procedures, techniques, and theory.
