Corequisite: Organic Chemistry 2. Attendance: Mandatory, there will be no make-up lab sessions. A missed lab will automatically count as a zero. Any student who misses 2 labs without providing a documented, verified reason, and without contacting the instructor, will automatically fail the course. Each lab missed will result in a grade of 0 for that lab assignment. Textbook: Integrated Techniques in Organic Chemistry II, N.

Course Goals: The objective of the laboratory component of Organic Chemistry 2 is to introduce key techniques that will enable the student to perform organic chemistry on the microscale. In addition, the laboratory portion of the course will serve to emphasize key concepts presented in lecture. Laboratory Supplies: Safety glasses with side shields (for sale in the chemistry office). Preparation: You are required to come to the lab prepared to begin the experiment. The lab is no place to start wondering what to do. Being unprepared is both dangerous and wastes time. Therefore, a prelab must be completed before beginning lab. The prelab must contain any reagents (MW, melting point, boiling point, density, etc.) a chemical equation (only for chemical reaction), and a brief but detailed summary of the days experiments. All of this will be completed in the e-notebook. This must be done before lab. Failure to complete the pre-lab will result in the student being unable to complete the lab and a grade of 0 will be assigned. Laboratory Dress Code: Safety glasses must be worn at all times while in the lab, even if you are not performing an experiment. You will receive one warning for failure to wear safety glasses and the next infraction will result in ejection from lab with a grade of zero. Shoes worn in the laboratory must cover all of your feet (no open toe shoes, no slippers with heels exposed, or any shoe that does not completely cover your feet). You must wear long pants to lab that adequately cover your legs (no ankles showing). No sleeveless shirts or shirts that leave the mid-section exposed are allowed. Long hair should be pulled back to keep it from falling over the laboratory bench. In general, wear clothing that covers as much skin as possible and that you are not too worried about getting stained. Grading: The laboratory grade will be composed of prelab quizzes, lab reports and post lab questions, and a laboratory final. In order to obtain a lab grade, you must complete all lab assignments and complete the check-out. The grading will be on a standard ten-point scale (A, 90-100; B, 80-89; C, 70-79; D, 60-69; F, 0-59).

For instance, if there is a recrystallization, be sure you have read that technique section. The lab e-notebook must be completed prior to entering lab. You must have all of the pre-lab assignments completed. Failure to do so will result in you being prohibited from entering lab and a grade of 0 will be assigned.
Lab Reports: All lab reports must contain the following sections in this order to receive full credit (lab reports that are not ordered correctly will receive a point deduction). 1. Title 2. Balanced Chemical Equation 3. Mechanism (where appropriate) 4. Table of Reagents 5. Pertinent Safety Information 6. Outline of the Procedure 7. Data and Observations 8. Results and Discussion (typed) 9. Conclusion (typed) 10. Answers to Any Questions Items 1-6 should be in your laboratory e-notebook before each lab. Title: This should include a brief description of the lab that you are doing. Balanced Chemical Equation: Only list the major reaction here, no side reactions or extra steps used in the workup. Mechanism: A full and detailed stepwise mechanism must be listed when necessary. Table of Reagents: Here, important physical data should be listed (molecular weight, boiling point, melting point, density, etc). Most of the data can be found in the CRC Handbook of Chemistry and Physics, The Merck Index, or the Aldrich Catalog. In addition, the information can mostly be found by doing a Google search. Important: do not waste time for unimportant information such as the boiling point of benzoic acid, only the melting point and molecular weight would be needed here. Safety: You should list any safety precautions needed for the chemicals that you will be working with during the experiment. Procedure: Your notebook should contain an outline of the procedure for the lab that you are completing. Bullet points will suffice here. Data and Observations: As you perform the experiment, you should write down all data (weights, volumes, temperatures, melting points, boiling points, etc.) as soon as they are taken and record all observations (notable changes during the reaction of workup, the color and consistency of the product, anything that went wrong, etc.). Write down any important observations with short phrases like while refluxing the color changed from clear to green or the solution bubbled when NaOH was added as soon as they happen.
Draw simple pictures to help illustrate any observations, apparatus descriptions, and any modifications. You can do this by uploading pictures from paper. Results and Discussion: Describe what actually happened in your experiment. This is the section where you make sense out of things-why they worked or didn t work. Discuss any changes made to the procedure and any problems encountered. You should include any graphs and yields, giving a discussion of each. Always discuss why your yield deviated from what you would expect. Conclusion: Write what you can conclude from the experiment in two or three sentences. Note: This report will follow the format of an ACS journal. You will be given a template to include all sections at the appropriate time. More information will be given regarding this report at a later date.
