III. COURSE DESCRIPTION:
The lab for this course is designed to teach the most common techniques used in the field of Organic Chemistry. The approach is an investigative one where theories that govern techniques are conceptualized through hands-on experience. The students will learn how to perform the following techniques: extraction, re-crystallization, melting point, distillation, chromatographic separation, infrared spectroscopy and synthesis. In addition, an introduction to chemical literature will be emphasized.

COURSE OBJECTIVES: Upon successful completion of this course, the student should be able to:

1. perform safely and successfully the various techniques used in undergraduate organic chemistry.
2. conduct organic chemistry experiments, follow procedures, use common sense, collect data, analyze data, and make sound conclusions.
3. use the chemical literature to search for essential information in organic chemistry.
4. keep organized and coherent documents of all that occurs in the laboratory.
5. appreciate the complexity of planning, designing, and performing an organic synthesis.
6. appreciate the numerous and important applications of organic synthesis to our everyday life.
7. clean up chemical waste generated from each experiment using proper guidelines.
8. understand the use of spectroscopy in characterization and identification of organic structure.
9. emphasize modern and classical lab techniques in the elucidation of chemical structure

Academic Integrity

Academic integrityrequires that all academic work be wholly the product of an identified

individual or individuals.  Collaboration is only acceptable when it is explicitly

acknowledged.  Ethica conduct is the obligation of every member of the University

community, and breaches of academic integrity constitute serious offenses.  Since a lack

of integrity hinders the student’s academic development, it cannot be tolerated under any

circumstances. Violations include but are not limited to: cheating, fabrication, plagiarism,

and denying others access to information or material.  See USF Catalog for further

clarification and information on grievance procedures.

Laboratory Notebook

Purpose: A laboratory notebook has three main purposes:

1. To keep relevant data and observations for your personal references;
2. To be able to duplicate the same experiment as it was reported;
3. To establish the validity of the work being done and of patent claims in a research lab.

General Guidelines for Organizing Your Lab Report:

Special Needs

The University strives to be in compliance with Americans with Disabilities Act (ADA) regulations.  Students with disabilities who require reasonable accommodations to fully participate in course activities or meet course requirements are encouraged to register with the Office of Disability Services to discuss access issues.  Please call 815-740-5060 or visit the Library  L 214 to coordinate accommodations.

As a Catholic university rooted in the liberal arts, we are a welcoming community of learners challenged by Franciscan values and charism, engaged in a continuous pursuit of knowledge, faith, wisdom, and justice, and ever mindful of a tradition that emphasizes reverence for creation, compassion, and peacemaking.  We strive for academic excellence in all programs, preparing women and men to contribute to the world through service and leadership.
