Welcome to Chemistry 12A (5 units) Organic Chemistry Fall 2012, De Anza College Instructor: E-mail: Office Hours:
Dr. Vanessa Williams
[email protected], please use the course title in the subject line. TTh: 10:30 – 11:00 am, 2:30 – 3:00 pm, F 10:30 – 11:30 am, Faculty Space SC-1 (2nd floor), or by appointment
Course description: Chemistry lies at the foundation of many of the sciences and is plays an integral part of many entwined fields such as pharmaceuticals, chemical biology, polymer and materials development, chemical engineering, cosmetic research, food science, etc. The application of chemical knowledge is incredibly vast! This is the first quarter of a three-quarter organic chemistry sequence, which covers
fundamentals of organic chemistry. We will cover organic functional groups, structure and stability of organic compounds, as well as types of isomers and stereochemistry. Additionally, we will study organic reactions, using mechanisms to understand how a reaction works and to explain any region- or stereochemistry preferred. Moreover, once we have begun to fill our “synthetic toolbox” we will learn how to use retrosynthetic analysis in organic synthesis. We will spend some time reviewing bonding, kinetics, thermodynamics, and equilibrium in light of the reactivity of organic molecules. A set of lab experiments has been selected to compliment concepts covered in lecture. These will introduce important techniques used in organic synthesis – including methods for purification: extraction, distillation, recrystallization, and thin-layer chromatography (TLC). Furthermore, we will learn instrumental techniques routinely used to analyze and identify organic compounds: gas chromatography (GC), infrared spectroscopy (IR), mass spectrometry (MS), and nuclear magnetic resonance spectroscopy (NMR). Student Learning Outcomes: 1. Predict the product of a chemical reaction. 2. Apply principles of thermodynamics, kinetics, and equilibrium to organic reaction systems. 3. Generate logical stepwise reaction mechanisms. 4. Construct molecular structure from spectroscopic data. Meeting times/sections: This class is divided into three separate instructional periods: a lecture period devoted to the primary course material; a supplementary lab lecture period focusing on experimental techniques; and a lab period for conducting lab experiments. One registration code automatically enrolls you in all three periods. Everyone will have the same lecture period, but a different lab lecture and lab period depending on which code you used for enrolling. At De Anza College the lab and lecture cannot be taken as separate courses under any circumstances. Once you are enrolled you may not switch lab lecture or lab periods whether on a temporary or on-going basis. Chem 12A: CRN: Lecture: Lab Lecture: Lab:

Experimental Organic Chemistry: A Miniscale and Microscale Approach, 5th edition by John C. Gilbert and Stephen F. Martin (Thomson Brooks/Cole: 2011; ISBN 9781439049143 3. A scientific calculator that has at least log and exponential functions is required (~ $12). Graphing capabilities are not necessary. 4. 8.5 x 11 permanently bound laboratory notebook. 5. Laboratory safety goggles purchased from the De Anza Book Store. Other types of goggles will not be permitted. 6. A combination lock for your laboratory locker. 7. Latex or Nitrile Gloves available from the bookstore. 8. 5” x 7” index cards for in-class exercises. Registration, Attendance and Conduct: Registration: Due to safety concerns, enrollment in each section is strictly limited to 26 students per section. Class spaces are filled in accordance with the official class roster from Admission and Records, followed by the official wait list. Any errors with registration or status must be addressed directly to Admission and Records. Please note that if you are placed in a section from the wait list, you will not be assigned a laboratory locker or be allowed to perform experiments until you are officially enrolled in the class. Attendance: Attendance is expected during all lectures, all lab lectures, and all laboratory periods. Attendance will be done in the form of a sign-in sheet. You may sign in prior to or after lecture and it is your responsibility to make sure you sign in! Students are expected to be prompt and to leave only when lecture or lab is concluded. Arriving late to lecture is disruptive to the class and strongly discouraged. If you miss lecture, laboratory lecture, or a laboratory period for any reason within the first week of class, you will be dropped from the course. Two or more unexcused absences from lab will result in an automatic “F” grade for the entire course regardless of what your total number of points may be at the end of the quarter. If you are dropped from the course during the first week of class, your locker may be inspected and reassigned to another student. You will be held responsible for any broken or missing equipment prior to reassignment. Dropping the Course: If you choose to drop the course at any point during the quarter, it is your responsibility to withdraw from the course through Admissions and Records by the appropriate deadline. Failure on the student’s behalf to complete the drop/withdraw process will result in a grade of “F”. The instructor will not drop any students after the first week, or change any grades at the end of the quarter due to student’s failure to properly withdraw from a course. Furthermore, you are required to officially check out of your lab locker whether you remain in the course or drop the course. Failure to check out of lab by the scheduled checkout date will result in an administrative fee and a block will be placed on your future registration.

Conduct: It is my job to ensure that all students enjoy a supportive, respectful learning environment. The ringer on all cell phones and beepers must be turned off during lecture and lab. I have a zero-tolerance policy toward any speech or behavior that disrupts the learning environment or prevents any student from achieving their educational goals. This includes, but is not limited to, disruptive behavior in the classroom such as speaking over the instructor, interrupting other students, monopolizing the instructor’s attention such that other students cannot be served, disrespectful, demeaning, or discriminatory remarks of any kind, and any form of coercive behavior toward the instructor or other students. Any student who engages in such speech or behavior will be told to leave the class for the day, and if the behavior occurs a second time the student will be referred to the Vice President of Instruction for disciplinary action. Please notify the instructor if you need to leave the lab for any reason. Students are also expected to abide by the Academic Integrity policy as outlined in the De Anza College catalog at all times. Students caught cheating or plagiarizing on any assignment will be expelled from the course and receive a grade of “F.” If collaboration between students to cheat can be demonstrated, each student will receive this same penalty. Grade Evaluation: Your grade will be determined based on your total points obtained from lab assignments/reports, quizzes, exams and your final exam.

Lecture Exams: There are 3 lecture exams and one final exam. Material covered in lecture, in the assigned reading, exercises, and activities will be on the exam. Make sure you can do all the assigned homework without struggling. Exam questions will include some questions that are similar to chapter exercises in addition to conceptual questions and select questions that will challenge your understanding of the material (meaning you may have never seen this type of problem in the homework). Each lecture exam is worth 125 points, and is curved. No early, late, or make-up exams will be given.

The final exam is cumulative and is worth 250 points. The final exam must be taken during the time designated by admissions and records (can be found online): 12/12/12, 9:15 – 11:15 am. There will be no multiple-choice exams in this class. Exam Re-grade Policy: If you feel that any of your exams are graded incorrectly, you are always welcome to turn the exam in for a complete re-grade at the end of the lecture or laboratory period on the day the exam is passed back. Please do not talk to me to dispute the grading error or make me aware of what the error is, simply give it to me stating that you would like an exam re-grade. In fairness, the ENTIRE EXAM will be re-graded and a new grade will be recorded only if the re-grade score is at least +3 or -3 raw points of the original grade. Lecture Quizzes: There will be four unannounced quizzes throughout the quarter, but only your three highest quizzes will count toward your final grade. Further, these quizzes will be administered during the lab period. There will be NO MAKEUP QUIZZES. If for ANY REASON you should miss a quiz, it will automatically count as your dropped quiz score. Homework: For each chapter, required homework problems will be assigned and collected in class. Homework will be graded as (+), (-) or (0). A zero means that no homework assignment was turned in. A (-) means that the homework was turned in but not completed, and (+) means the homework is complete or mostly complete (>75%). All students sitting at a borderline grade (+/- 0.5 percentage points) will have their homework scores evaluated. If you have mostly (+), your grade will be bumped up or stay the same. If you have mostly (0), your grade will be bumped down or stay the same. Mostly (-) will not affect your grade. It is possible for your letter grade to be changed because of your homework! Extra Credit: There is the possibility for extra credit assignments, so stay tuned! They will be announced in class throughout the semester.

Laboratory Notebooks: You are required to maintain a bound laboratory notebook, dedicated solely to your lab work. Please do not take any lecture or lab lecture notes in your notebook. Each experimental procedure must be written in your lab notebook prior to performing the experiment. You may not perform a laboratory experiment unless
4
your laboratory notebook and procedure is prepared prior to the start of the lab lecture. Each lab procedure preparation is worth 5 points of the 20 points allotted for each lab report. Guidelines for maintaining your laboratory notebook and the grading of your procedures will be given by your laboratory instructor. Throughout the course of the experiment, data should be recorded IN INK in the laboratory notebook and this notebook only. Recording of data on any other media will result in technique point deduction. Additionally, a table of contents and table of hazards should be maintained throughout the quarter. At the end of every experiment, Professor Williams will inspect data and provide a signature. Each chemist should also sign and date each experiment entry upon completion. The notebook will be worth 15 points, and checked sometime toward the end of the term. Laboratory Lecture: Students are expected to attend all laboratory lectures and all laboratory sessions. You must complete all of the laboratory experiments, and you must also participate in the entire laboratory session in order to receive credit for both the laboratory notebook and the laboratory report. There are no make-up labs. If you are unexcused from a lab period or fail to perform any part of a laboratory experiment, you will receive zero credit for the corresponding lab report. It is also your responsibility to understand the theory and use of the chemicals and equipment for any laboratory period that you miss in order to be prepared for the laboratory final. If you have a medical emergency or some other emergency that prevents you from attending lab, you will be asked to supply written documentation in order for the absence to be excused. Be sure to contact the instructor as soon as possible if you miss a lab session. If you miss laboratory lecture or a laboratory period for any reason within the first week of class, you will be dropped from the course. Two or more unexcused absences from lab sessions will result in an automatic grade of “F” for the entire course. Laboratory Reports: There are 7 lab reports TOTAL, but only 6 will count toward your grade where the lowest score is dropped. Each lab consists of completing the laboratory preparation prior to lab in your laboratory notebook. This is worth 5 points and is due at the beginning of the lab period. Your lab instructor will share more details regarding the lab report format during your lab period. Lab reports will be due based on the schedule given to you by your lab instructor. No make-up labs or late lab reports will be allowed or accepted. Without exception all laboratory reports must be typed. Lab reports should be in your own words. Copying data, calculations, phrases or paragraphs from another student or the web is considered plagiarism/cheating and will be penalized following De Anza’s policy regarding academic dishonesty. In such instances, a score of “0” will be given for the assignment and the case also reported to the Division Dean for further action. Laboratory Quizzes: There will be 7 total quizzes, but only 6 will count toward your lab grade. For this reason, there will be NO MAKEUP QUIZZES for any circumstance. Quizzes may be announced or unannounced, and generally, will not be open notebook. They will be given at the start of a lab period; any students arriving late will not receive extra time to complete the quiz. Fair game for quizzes: procedural information, safety
5
information/chemical hazards, concepts, problems/calculations, and data interpretation. Each quiz is worth 30 points each for 150 points total awarded for quizzes. Laboratory Exam: There is one laboratory exam worth 100 pts. The laboratory exam will be given during your regularly assigned laboratory sessions, and will be written and administered by your laboratory instructor. The laboratory exam will be held during the last laboratory (check out) period. No early, late or make-up lab exams will be given.
Here are a few tips about studying for this course. 1) Read each chapter/designated sections carefully before coming to class. Not every detail will be covered in lecture, but you are still expected to understand the whole chapter. 2) As you read the chapter, attempt to do some of the corresponding in-chapter and end-of-chapter practice problems. Exam questions will often be very similar to the homework problems; therefore, make sure you can do all of these problems comfortably before an exam. Try to first do these problems without looking at the solutions. This is very important since you will not have a solutions manual on an exam!! Educational research has shown it is just as important for your brain to see mistakes as it is for your brain to figure out the correct pathway. It also tells us that you must see the same information at least three times within 48 hours in order to retain that information. 3) DO NOT FALL BEHIND WITH THE READING OR HOMEWORK!! This is the number one mistake you can make. Concepts in chemistry are like building blocks. Initially, you learn one topic to build up to larger concepts. If you are shaky on a topic early on, your whole foundation will be unstable. To avoid this, try to read ahead of the scheduled lecture topics and keep up with the homework. 4) In addition to completing the homework, it is also recommended that you discuss ideas and concepts with your peers in study groups. Teaching and having to explain something to someone else will solidify the concepts for yourself, and you will truly master it. When you are also stuck, it is helpful to learn different perspectives and ways to approach a problem – you gain all these benefits by studying with others! 5) Come to office hours to discuss ideas with me as well. More importantly, as soon as you have a question, please come see me! I am always glad to help, and it will only make things more difficult for yourself if you do not get questions answered – especially early on. 6) Get outside help – tutoring! There are numerous places you can get tutor help. If you are able to hire an outside tutor, a reputable site like Wyzant.com is a good place to look for tutors in all subjects. You can also get free tutoring from the Student Success Center on campus (see below)

SUPPLEMENTAL: Partial List of Laboratory Safety Procedures (Additional Information is found in the Laboratory Manual) o
Students must comply with all safety procedures and precautions when attending a laboratory session.
o
There are no provisions for making up a lab; therefore, you are expected to attend all scheduled lab sessions.
o
You must have your laboratory procedures written prior to starting an experiment. Lab notebooks will be checked during lab and will be awarded between 1-5 points depending on completeness.
o
Laboratory notebooks must be written in ink and all data must be written in the laboratory notebook. Scraps of paper containing data will be confiscated. Do not use “white-out.” Use one line to cross out incorrect data.
o
Lab lecture will consist of a discussion concerning safety for the experiment being conducted that day as well as information regarding experimental techniques.
o
Eating and drinking is not permitted in the lab. Do not bring food or drinks to the lab even if they are in closed/sealed containers.
o
If you are pregnant or think you are pregnant, it is your responsibility to consult with your physician before taking this course and performing the laboratory experiments.
o
You must wear OSHA approved safety goggles and gloves at all times while in the laboratory. Failure to comply with this rule will result with your being expelled from the course and receiving a grade of “F.”
o
Appropriate attire must be worn in the laboratory.
Shorts, open toed-shoes, and sleeveless shirts
(“spaghetti straps”) are not considered safe clothing for the laboratory. Clothing made of natural fibers is less of a hazard than those made of synthetic fibers. o
Do not begin the laboratory experiment (e.g. place any chemicals or glassware on the lab benches, turn on Bunsen burners, etc.) until the safety introduction is complete and everyone is wearing their goggles and gloves. The instructor will let you know when it is time to begin the experiment.
o
In some cases it will be necessary for the instructor to examine your “set up” before you begin the experiment. In these instances, the instructor will inform you of proper procedures at the beginning of class.
o
If you come into contact with a chemical flush the affected area with water immediately for 15 minutes. Depending on the degree of contact with the chemical and the location on the body you may need to do this in the sink or safety shower. When using the safety shower you must remove the clothing over the area that has come into contact with the chemical. The instructor will ask the other students in the class to leave the room for privacy.
o
You will be wearing safety goggles at all times, but should you get a chemical in your eye, flush your eyes in the eye wash for at least 15 minutes.
10
o
If your clothing or hair catches on fire use the safety shower immediately. If this is not possible “stopdrop- and –roll.”
o
If you are hurt or think you have come into contact with a chemical, notify the instructor immediately (or send a lab partner to fetch the instructor) while following proper safety procedures.
o
Know where the eyewash, safety shower, and fire extinguishers are located. (You should be able to do this with your eyes closed!)
o
Chemicals should never be taken back to your lab bench. They must be kept in the fume hood in their proper storage containers. All chemicals and waste bottles must be capped after use. Never leave a chemical bottle or waste container uncapped.
o
