Heartland Community College Math and Science Division Course Syllabus and Policies Spring 2013 Semester Organic Chemistry II (Lecture & Lab) CHEM 242 Catalog Description Prerequisite: CHEM 241 or equivalent. A continuation of Organic Chemistry I. This course will focus on the synthesis, reactivities, and mechanisms of various organic reactions. Topics will include the study of aldehydes, ketones, carboxylic acids, esters, amines, amides, aromatic derivatives, and biologically important molecules. One three hour lab each week will emphasize the synthesis, characterization, and identification of organic compounds that feature different functional groups. Contact Hours Credit hours: 5, over 16 weeks (January 14, 2013 – May 16, 2013) Lecture hours: 4/week (MW, 1:00 – 2:50 p.m.) Lab hours: 3/week (W, 3:00 – 5:50 p.m.) Instructor Information Instructor: Dr. Nicola J. Burrmann Phone number: (309) 268-8652 Email address: nicola.burrmann@heartland.edu Website: http://employee.heartland.edu/nburrman Office: ICN 2022 Office hours: MW, 12noon – 1 p.m., TR, 10 – 11 a.m.; T, 2 – 3 p.m. Transferability Information CHEM 242 fulfills 5 semester hours of elective credit for the A.A., A.S. or A.A.S. degrees. It should transfer to most colleges and universities as an elective course. However, since it is not part of the General Education Core Curriculum described in the Illinois Articulation Initiative, students should check with an academic advisor for information about its transferability to other institutions. CHEM 242 should articulate as the equivalent of the IAI baccalaureate major course CHM 914. Refer to the IAI web page for information as well at www.itransfer.org.

Burrmann (2012) Duplicating (e.g. carbon copy) lab notebook A scientific or graphing calculator Safety goggles or glasses (provided by HCC or supply your own) Required Reading and Writing This course will require approximately 600 pages of text from both the lecture and lab textbooks over a 16-week period. Written analysis will be required in the form of problem sets, quizzes, exams, and both formal and informal laboratory reports. Course Description and Learning Objectives This is the second course of a two-semester sequence intended for those students with an interest in a science major, such as chemistry, chemical engineering, biology, or physics, or a preprofessional major, such as pre-medical, pre-dental, or pre-pharmacy. This course covers the detailed mechanistic explanations of a variety of synthetic organic reactions, as well as the prediction of reagents necessary to bring about a series of synthetic transformations. These skills will ultimately be used in the planning of the total synthesis of a diverse group of organic compounds. By the end of this course, students will have developed an understanding of the fundamental concepts of organic chemistry, as well as critical thinking and analysis skills. While learning and understanding the core concepts of organic chemistry will be vital for success, emphasis on exams, quizzes, and problem sets will be placed on critical thinking and problem solving abilities. This means that while some questions on these assessments will be based directly from material presented in class (PS1, PS2), many problems will ask you to use or interpret your knowledge in a new, related way (PS3, PS4, CT1, CT2, CT3). This will be achieved by - applying concepts of stability and reactivity to conjugated and aromatic systems, determining the chemical reactivity of aromatic molecules with both electrophiles and nucleophiles, understanding the oxidative and reductive reactivity of alcohols, aldehydes, ketones, and carboxylic acids, reviewing and expanding upon the reactivity of alcohols, ethers, and analogous sulfur-containing compounds, understanding the properties of a variety of carbonyl compounds, including aldehydes, ketones, carboxylic acids, esters, anhydrides, and acyl halides, determining the chemical reactivity of these classes of carbonyl compounds, involving wide range of nucleophiles and electrophiles, understanding the methods for preparing carbon-based nucleophiles, such as organolithium and Grignard reagents, then reacting these nucleophiles with a variety of electrophiles, understanding the methods for preparing and reacting enols and enolates, understanding the properties and nucleophilic reactivity of amines, as well as their preparation using reductive and substitution reactions, and applying these reactions to biologically-relevant molecules, like carbohydrates and amino acids. Date Prepared: December 18, 2011 njb Date Revised: January 8, 2013 The lab portion of this class will highlight concepts presented in lecture using practical techniques, including characterization, synthesis, and purification of compounds. A large portion of report grades will be based on effectively analyzing and defending results obtained in the laboratory (CO1, CT1), through either informal or formal laboratory reports. Method of Evaluation (Grading System) Grades will be determined by a combination of problem sets, quizzes, exams, and lab work ("assessments"). Points will be distributed as follows: Assessment Number of Each Assessment 6 5* 3 1 9 12 2 Lecture Problem Sets Quizzes Lecture Exams Lecture Final Exam Lab Reports Lab Technique Lab Exams Total Points Possible * Lowest quiz score will be dropped. Points Possible (Each) Total Points 25 25 100 200 Variable (See Schedule) 3 40 150 100 300 200 134 36 80 1000 Grades will be based on a set scale: A: ≥ 85.0% B: 75.0 – 84.9% C: 65.0 – 74.9% D: 60.0 – 64.9% Incompletes will only be given in rare circumstances, approved by the course instructor.

Attendance for the lab portion of the course is required. Quizzes and lab work cannot be made up for any reason. If you miss a quiz, this will count as your dropped quiz. If you miss lab work, you will lose your technique points for the day, and you may obtain lab data from one of your peers to complete your lab report. Note that it is your responsibility to obtain this data and that your lab report will be assessed a penalty of 20%. Lecture and lab exams cannot be made up after their scheduled date, except under highly extenuating circumstances, as approved by the course instructor. If you know well in advance that you will miss an exam, talk to the course instructor to schedule to take your exam before the scheduled date. Please remember to either turn off or put your phone into silent mode before the start of each lecture and lab, in order to minimize disruptions. The course instructor reserves the right to dismiss repeat offenders from a class period after an interruption. Lecture Homework, Problem Sets, Quizzes, and Exams One full class period will be devoted to each exam. Quizzes will be given at the beginning of class periods, with 30 – 45 minutes devoted to the quiz, depending on the content and difficulty level. Use of molecular models on quizzes and tests is allowed and encouraged; however models may not be shared between students during quizzes and tests. Course exams and quizzes will consist of questions in a variety of formats, including (but not limited to) multiple choice and free response. No partial credit will be given for multiple choice questions. Partial credit will be given on the free response questions, so be as complete as possible! Your lowest quiz score will be dropped at the end of the semester. Selected homework problems assigned for each chapter in the textbook are completely optional. No grades or point values will be assigned to homework problems. The content of these questions will usually be highly reflective of the content included in quiz and exam questions. Therefore, completing the supplemental homework is strongly recommended, as doing so will give you an opportunity to demonstrate your mastery of topics presented in class. Six problem sets will be given out during the semester, and these should be completed for course credit. The textbook and internet are acceptable resources of information for these problem sets. While working on these problem sets with a group of peers is strongly encouraged, be sure to record all answers in your own words – Do not plagiarize! (Please see next section on Academic Integrity and Plagiarism. Working together with peers means that you should work together, step-by-step, until you arrive at an answer or work independently and then compare work at the end. However, it is unacceptable to directly copy someone else's answer without understanding why the answer is what it is and how it was derived. Date Prepared: December 18, 2011 njb Date Revised: January 8, 2013 Laboratory Information The lab portion of this course will consist of ten experiments (with reports and technique assessments), two problem sets, and two exams over a 16-week period. Each of the labs will be related to the content presented in the lecture portion of the class. Lab grades will be determined by a combination of lab reports, lab problem sets, technique, and exams. The point values of each lab report, problem set, and exam are found in parentheses on the lab schedule.

These exams will cover experimental concepts and techniques that have been used in lab prior to the date the exam is given. Possible exam questions include, but are not limited to, calculating percent yields or other information (as done in lab), identifying glassware or an entire experimental setup, or describing a type of experiment that would be used to achieve a particular result. Lab Reports A written laboratory report (either formal or informal) will be required for each experiment performed. Guidelines for the written laboratory reports are detailed below. Laboratory reports are always due at the beginning of the next lab period, after all components of the experiment are completed. Reports may be turned in one day late and will be assessed a 20% penalty. Reports will not be accepted more than one day after they are due. Keeping a Lab Notebook Use either blue or black ink in your laboratory notebook. Use a single strikethrough to cross things out – don’t scribble! It is very important to be neat and legible. If I cannot read your handwriting, I cannot grade you effectively. Use a two-column format for writing out procedural information. (See below for more information on writing procedures.) Spelling and grammar do count. If a word is given to you in the laboratory manual, it should be spelled correctly! Do not use abbreviations unless it is the chemical formula for a common reagent; e.g. HCl for hydrochloric acid is fine. Set off sections (Reaction, Discussion, etc.) with headers, preferably capitalized or underlined, so they’re easily distinguishable on the page. Informal Lab Reports Informal lab reports will consist of turning in the duplicate pages from your lab notebook, as well as completed and analyzed spectral characterization data for the experiment. The information in the following paragraphs should be recorded in your lab notebook. Be sure to leave some space in the margins for instructor comments. Before Lab Read through the materials pertaining to the day’s topic and complete the “Pre-Lab” portion of your notebook. (See below for more information on what should be included in your Pre-Lab.) The Pre-Lab must be approved and initialed by the course instructor before beginning the experiment. The following components should appear in a complete Pre-Lab: - - Basic Information: Experiment title, your name and your partner’s name, and the date. Purpose: Two to three sentences explaining why you are doing this experiment. The purpose can include learning a new technique, completing a successful reaction, or achieving a specific end-result. The purpose should be as specific as possible. Do not copy directly from the lab text! This is plagiarism! Reaction: A structural equation should be written for each reaction, if applicable. A mechanism is not required. Date Prepared: December 18, 2011 njb Date Revised: January 8, 2013 - - Reagent Table: This should be done as a table. This should include the name of the reagents being used (excluding solvents and those used for extractions or washing) and their molecular weights, densities (for liquids), and/or melting or boiling points. You should also include the amount of each reagent suggested in the lab manual, in grams or milliliters, as well as moles or millimoles. (After your experiment is complete, you should go back and add in the amounts of each reagent that you actually used.) Physical data (densities, etc.) can be found at http://www.sigmaaldrich.com or a variety of other places on the internet. Remember to site all sources! As a general rule of thumb, if the reaction cannot occur without the use of a specific chemical, the chemical should be included in the reagent table. In other words, no substitution for the chemical can be made and still have the reaction occur. Pre-Lab Questions: Write out the answers to the pre-lab questions that can be found in the manual or provided by the course instructor, if there are any. Procedural Outline: Write out an outline of the procedure for the experiment, using the lefthand column in your lab notebook. This procedure should include procedural steps and amounts of chemicals. Write down what you will be doing (Use an oil bath to heat the flast), how much chemical you will use (Add 25 mL of hexane, followed by 1.7 g Mg shavings, etc.). Draw or refer to diagrams of your set-up. Do not just copy the procedure given to you! I should be able to replicate your results based on this section of your report! During Lab - The course instructor will give a brief explanation of any new content, as well as an overview of what to expect during the experiment. - The experiment for the day should then be completed in its entirety, or to the point specified by the course instructor. When working through the procedure, be sure to record any procedural changes, data, and observations in the right-hand column of your lab notebook, opposite to the relevant procedural point in the left-hand column. (With the example above: 25.4 mL hexane, 1.746 g Mg; solution turned yellow and cloudy, etc.) Make sure to include all observations! - Do not write data, etc. in other notebooks, in the lab manual, or anywhere other than in your lab notebook! - Technique: The course instructor will be observing you in lab and assessing your safety, neatness, ability to follow instructions, and improvement in the laboratory. Up to five technique points will be awarded for each lab period. Points will be deducted at the instructor's discretion for using improper laboratory technique. After Lab - Perform all necessary calculations. Be sure to show work to receive partial credit, in case your data was incorrect. Write out all of the steps for a calculation that needs to be done. Label the calculations for what they are (percent yield, etc.) and be neat. If the course instructor cannot determine what all numbers pertain to, credit will not be given. - Analyze any spectra obtained for characterization purposes. Clearly label relevant portions of the spectra and provide a brief explanation of what this data indicates for the relevant compound. Draw the structure of your target molecule and assign peaks to structural elements, if applicable. This must all be done directly on the spectra! Date Prepared: December 18, 2011 njb Date Revised: January 8, 2013 - - Write an Error Analysis. Describe what went wrong, if anything, during the experiment. Explain why percent yields or purities were low, or other recorded data does not match expected values (if applicable). Don’t make things up as to what you think happened. If some of the product mixture spilled, say so. Don’t say that something “could have happened” and therefore “the results weren’t as good as they could have been.” Do not repeat procedural details here, unless they specifically impacted your results or to explain why a certain step was done. Write out the answers to any post-lab questions that can be found in the manual or provided by the course instructor, if there are any. Formal Lab Reports For one experiment, a formal lab report will be written. This report must be typed and doublespaced, with one inch margins on all sides. You should use 12-point, Times New Roman font and paragraph form. Write in past tense (since the experiment has already been completed), and spelling and grammar do count. These formal reports will have identical components as listed above for the "Before Lab" and "During Lab" sections, which do not need to be typed. Turn in the duplicate pages from your lab notebook for these sections. For the "After Lab" portion of the report, which should be typed, include: - - - - Title Page: Include your name, a title for the experiment, the course number, and the date on which the report is due. Introduction: This section should develop the theory behind the experiment, including the reaction that is being performed and why it is important. Discuss the unique aspects of the experiment. A mechanism should be included in this section. Any idea that is not expressly your own should be referenced. (See “References” below on how to do this.) Results: This section summarizes the results obtained from the experiment. Perform all necessary calculations, showing work, in your lab notebook, and summarize the final data in a table within the formal report. Analyze any spectra obtained for characterization purposes, as described above, and attach at the end of the report. Do not discuss what your results mean in this section. Simply state them in an organized manner. Discussion: This section is used to discuss what the experimental results mean and to show understanding of the purpose for the experiment and the results obtained. Discuss why the results turned out the way they did. Determine how accurate your data is by comparing experimental values to theoretical values. Make sure to reference where you obtained your theoretical values from. (See “References” below on how to do this.) Include the Error Analysis for the experiment here. Post-Lab: Type out the answers to any post-lab questions that can be found in the manual or provided by the course instructor, if there are any, using paragraph form. References: References are important for giving credit to data or ideas that are not your own. Within the paper itself, use a superscript to denote a reference. At the end of your report, insert a line or other indicator to show that the report itself is complete. Then reference the work (according to ACS format) as follows: (Within the introduction section…) Thin-layer chromatography is a useful technique for following the progress of reactions.1 Date Prepared: December 18, 2011 njb Date Revised: January 8, 2013 (Or within a discussion section…) The observed melting point range of the unknown neutral compound in Unknown B was 67-71°C, which agrees closely with the theoretical melting point range of biphenyl, 68-70°C.2 (After your conclusion…) 1 2 Calimente, D.S.; Strand, S.M.; Chang, S.C; Lewis, D.E.

Academic Integrity and Plagiarism All work submitted for grading should be solely your own. While working on homework with a group of peers or using a variety of resources (textbook, peers, internet) for studying or lab work is strongly encouraged, plagiarizing information will not be tolerated. Plagiarism is defined as taking another person's ideas or work and presenting them as your own. This can include copying or paraphrasing text from another source, whether it be printed (textbook or internet) or verbal (peer). If other sources are used in the completion of your lab assignments (physical data, pre- or post-lab questions), cite your sources with a textbook title and page number or website address. Plagiarism is considered a serious academic offense and violates the fundamental principle of academic integrity. Heartland Community College allows for a variety of disciplinary responses to plagiarism or other examples of academic misconduct, including course failure, suspension, or expulsion from the College. Examples of academic misconduct can include, but are not limited to, plagiarism, cheating, falsification or misrepresentation of data or academic records, and assisting others in acts of academic misconduct. Further examples and definitions for academic misconduct violations can be found in the college catalog. The penalty for cheating on any course exam will be dismissal from the course with a failing grade (F). A letter may also be placed in the student's permanent file at Heartland Community College, at the discretion of the course instructor. Note that these decisions can be appealed based on the appeals process found in the Heartland Community College Student Handbook. Date Prepared: December 18, 2011 njb Date Revised: January 8, 2013 Tips for Success Study regularly and often, ideally every day. A large amount of material will be presented, and the difficulty of these concepts will vary. Reading the corresponding sections of the textbook and completing supplementary problems should greatly improve understanding of the material discussed in class. Do not "cram" right before a quiz or exam! Cramming will only allow very minimal amounts of memorized information to be stored into your memory. As a majority of the quiz and exam content will be based on giving free response explanations or extensions of material presented in class, it is highly important that you learn not only the information itself, but also what it means and how it's useful. When working through suggested homework problems, do not look at the solutions until you have worked through the problem to the best of your ability and written down an answer. It's extremely easy to read a problem, immediately look at the answer, and think "That makes sense." Taking the time to work through the problems and write down answers will serve as superior learning tools to show how much of the course content is truly understood. It is strongly recommended that you purchase and use a model kit while reading through the textbook and working on homework and problem sets. It can be difficult to visualize twodimensional pictures of models as three-dimensional objects; however, this ability to visualize is very important to determine molecular structure and, ultimately, reactivity. Model kits may also be used on quizzes and exams.
