Monday and Wednesday Tuesday and Thursday 8: A continuation of Organic Chemistry I. Emphasis on the classes of aliphatic and aromatic compounds not previously discussed; spectroscopy; the use of instrumentation in organic chemistry; and introduction to the chemistry of carbohydrates, amino acids, proteins, and natural products.

Emphasis is placed on techniques, properties and reactions, and reinforcing principles offered in the lecture portion of the course. You are free to use a current or older version of this text, or another book altogether.

Do not attempt this course without a text. They are not as useful this semester as they were for Organic Chemistry I. So, if you do not already have a set, I would not recommend you buy one now.

An outline of the lecture notes for students can be found in Blackboard. The instructor will pass out the first unit of notes. After that, students are expected to print out their own notes. Recommended homework will be assigned to each unit, but not graded.

Exam questions will come from the homework as well as lecture notes, so it is suggested you work all the assigned problems. Answer keys to the homework are available on the course Blackboard website.

Ancillary materials are available on my website. There will be five regular exams. All exams will be given in the testing center during the tentative dates shown below. Grades may be curved at the discretion of the instructor. Make-up exams may be given with prior notice or under special circumstances e.

There will be a point penalty on exams given, for whatever reason, after the set exam dates. A comprehensive final will be given on the last day of class.

The final exam is optional. You can take this exam if you wish to replace a lower grade on a previous exam with the grade from the final exam. If you take the final exam and it is the lowest grade, it will be dropped.

Each exam is worth points. You will be graded on your 5 highest exams. There is not extra credit work available. Grading for the lecture follows a standard curve: Ethers and Epoxides Aldehydes and Ketones Enols and Enolates Carboxylic Acid Derivatives Amino Acids, Peptides and Proteins You are not required to attend lecture; however, your life will be so much easier if you do attend class.

Please turn off cell phone ringers during lecture and lab. If you miss an exam, you need to contact me as soon as possible.

I always grade exams within two days of the deadline, and return them promptly. Once exams are returned, there will be no chance for a make-up.

This policy applies to both lecture and lab. 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 April 22, NaBH4 (sodium borohydride) is a versatile and useful reducing agent in organic chemistry, however will only reduce carbonyl groups of aldehydes and ketones.

Experiment Isopentyl Acetate 19 October Introduction: The purpose of this experiment is to prepare isopentyl acetate by direct esterification of acetic acid with isopentyl alcohol.

After refluxing there is an isolation procedure where excess acetic acid and remaining isopentyl alcohol are easily removed by extraction with sodium.

Preparation of Vanillin Acetate

Lignin is a complex polymer that gives rigidity to trees and other woody plants. After cellulose, lignin is the second most abundant organic material on earth.

Vanillyl alcohol, which is made by the reduction of vanillin, shows promise as a renewable starting material for the synthesis of biologically active molecules and flavoring ingredients.
