Exams will be announced in class.GRADING: A one-hour examination will be given once a month. At the end of the semester,your lowest exam score (Exams I, II, or III) will be dropped and not be counted towards yourfinal grade (your final examination grade will be counted towards your final grade).

NO MAKEUP EXAMS WILL BE GIVEN. If an exam is missed for any reason, that will bethe one not counted.All students must take the final examination.The grade for this course will be computed as follows: two hour exams (25% each) + final exam(50%).Your letter grade will be calculated at the end of the semester and will be based on a class curve.Regardless of this curve calculation, any final scores that are below 40% of the total points (

Welcome to Organic Chemistry!COURSE GOALBy the end of this course, students should be able to communicate both graphically and verbally theproper starting materials, reagents, and products necessary to complete successful synthetic organicreactions according to the rules outlined by the molecular orbital theory and valence bond theory.OBJECTIVESBy the end of this course, students should be able to:1. Identify structures using both IUPAC and common nomenclature.2. Draw the correct starting materials, reagents, or products that complete successful reactions.3. Evaluate the steps involved in organic reactions using mechanisms.4. Know several research opportunities available to undergraduate students.How and what to study:Many students are not quite sure exactly how to best study organic chemistry. As the final grade of thisclass is looked highly upon by higher education institutions such as medical schools, it is imperative thatyou’re studying at the highest level possible. Studying organic chemistry requires a certain level ofcritical thinking that is imperative for performing well on a test. Here, I outline a procedure that I hopewill help you achieve the highest grade earned according to your level of studying.1. Draw, draw, draw! There will be reactions and structures on your tests that you have never seenbefore. Only good practice at drawing new structures will allow you to succeed in synthesizingor evaluating these new compounds. While you’re studying for the examinations, use only apencil and many sheets of white computer paper. Not worrying about making mistakes andstarting over when mistakes are made is also crucial.2. Practice! Like learning a new language or how to play a new musical instrument, learning theconcepts of organic chemistry is an art form that requires frequent practice. Cramming forexaminations may work for other courses, but it has been proven to be ineffective for receivinggood marks in organic chemistry.3. Study in groups! Being able to communicate the language of organic chemistry is crucial foryour success on examinations. There is only one way to practice this communication: study witha friend. Studying in groups should not be your only method, however. You should also studyby yourself to fully grasp the concepts.4. Understand, don’t memorize! One cannot perform well on an organic chemistry exam utilizingmemory alone. As previously mentioned, there will be structures on the tests that you have neverseen before. And one cannot memorize something they’ve never seen before!5. Think small! On the examination, there will be portions of molecules that may not be pertinentto the question at hand. Focus on the important parts of the compound involved in the chemistry.Like a doctor trying to diagnose a patient, one must whittle down any extraneous information tofind the correct answer.
