Please include “CHEM252” in the subject line. Recitations: Please make sure you are registered for one of the following sections.

Section 611 11:15 - 12:05 pm MWF HAH 104

Note: CHEM 254 (Organic lab) is a parallel but separate course. If you have questions, contact the lab instructor, Dr. Rick Hartung. (326 Hamilton, rhartung2@unlnotes.unl.edu).

Prerequisite: “C” or better in CHEM 251 and CHEM 253 or permission of the instructor.

A student taking a three credit course in summer should expect to spend an additional two hours

per one hr of lecture a week on coursework outside the classroom.

Textbook and Course Materials:

1. Organic Chemistry, 7th edition, L.G. Wade (Pearson Prentice Hall, 2010). CourseSmart eTextbooks are available on the bookstore's website and/or on the bookshelf, right next to the printed books - look for the Jumpbooks logo when purchasing eTextbooks. When your purchase is complete, you will be given a redemption code and access instructions. The subscription begins as soon as you access your CourseSmart book from the Jumpbooks website. http://www.coursesmart.com/IR/2665171/9780321598745

2. Registration to ACE electronic homework system will be required-ACE registration is free.

3. The Study Guide and Solutions Manual (Wade) is helpful but not required.

4. A set of molecular models is highly recommended. It is often difficult for students to learn how to visualize a molecular structure in three dimensions. Models will almost certainly help. If you want to take a look at models before buying some, come by the Resource Center or my office.

5. A PRS transmitter “clicker”, which will be used for in-class discussions and quizzes. Website: Materials related to this course, including this syllabus, announcements, course documents, exam keys, and grades will be posted on Blackboard: http://my.unl.edu Be sure to check and update your email address associated with Blackboard. Academic Honesty:

Any case involving academic dishonesty (see "Code of Conduct" in Undergraduate Bulletin) will result in a failing grade for the student(s) involved and will be reported to the Director of Student Judicial Affairs.

Course Objective:

Chem 252 is the second semester of organic chemistry and is designed to follow a one-year course in general chemistry and a semester of organic chemistry (Chem 251). It assumes a general knowledge of atomic structure, chemical bonding, acids/bases, reaction stoichometry, equilibria, transition states, free energy, naming organic compounds, recognizing functional groups, hybridization, shape of molecules, properties, importance, and reactivity of some common functional groups: alkanes, alkenes, alkynes, alkyl halides, resonance, organic intermediates (carbocations, anions and radicals), fundamentals of organic synthesis and functional group transformations, drawing detailed mechanisms, Addition reactions of alkenes, and SN1, SN2, E1 and E2 reactions of alkyl halides and radical substitution reactions. CHEM 251 should have provided you with a strong introduction to the basic principles of organic chemistry which you will use extensively during this course. You will need to review material that was covered in 251 as we progress with the course especially if you have taken it a while back or have forgotten some of the key concepts.

Most biological processes involve organic chemistry; understanding most biological processes

at the biochemistry level requires knowledge of organic chemistry. This course is a continuation of the chemistry of carbon compounds with emphasis on the chemistry of important functional groups that are found in biological systems.

The second semester course (CHEM 252) will focus on spectroscopy, synthetic chemistry of

carbonyl compounds (aldehydes, ketones and acid derivatives) and on the chemistry aromatic compounds.

Overall, the study of organic chemistry teaches a logical pattern of thinking and problem solving that is prized in many fields.

Grading: Grades will be based upon:

Clicker questions 50 pts (during recitation) Electronic Homework (ACE) 70 pts Midterms (2 x 150) 300 pts (in class 120 mins) Comprehensive Final 200 pts (in class 150 mins)

Grading Scale: Over the years, the average GPA for CHEM 251 has ranged from 2.25 to 2.75; the actual average grade in a given course can vary tremendously with the background, talent, and work ethic of students in that course. If your score falls in a given bracket (below), you are guaranteed to receive at least that grade. A > 90% A- >87% B + >83% B >80% B- >77% C+ >73% C >70% C- >65% D > 60% D- > 57% Incomplete, P/NP, Add/Drop, Withdrawing: An incomplete (I) grade will only be considered for a student who has completed the majority of the course and is unable to complete the course due to health reasons, military service, hardship or death in the immediate family. The course will follow standard UNL policies and deadlines for add/drop, P/NP, and withdrawing. Recitation: Recitations will focus on problem solving and reviewing material that is being covered in class.

Exams: (Exams will draw from lecture, text, and assignments. The final exam will be comprehensive.

Molecular models may be used during exams. No other notes, materials, or electronic devices are permitted. Phones and computers must be turned off during the exams; no communication of any sort is permitted.

Missed Exams: In any class this large, there will be emergencies that cause students to miss exams. In the event of a verified emergency, the student is to contact Dr. Chatterjee in person and arrange for a make-up exam as soon at possible.

Graded exams will be available in the Resource Room, 228 HaH. Any alterations of exams submitted for regrade will be treated as academic dishonesty.

Finals will not be returned.

Clicker Quizzes:

The PRS or “clickers” will be used to facilitate classroom discussion as well as to administer short quizzes during many/most lectures on materials presented in the previous lectures. This will be done through the PRS or “clicker” system. You will need to have a PRS transmitter (available through the bookstore; technical instructions are available at the Blackboard (www.my.unl.edu) web site. We will have a short clicker quiz in most recitations. You can enter the answer only once and points will be recorded only for correct answer.

There are no make-ups for missed clicker quizzes. Misrepresentation of identity on a clicker quiz (whether you pretending to be someone else or vis versa) is academic dishonesty.

Electronic Homework: Course: 252-Summer-2011 (1057) Course ID: 1057 Register at the ACE Organic web site http://chem-ace.unl.edu/ace/

I will enroll students once you have registered after which you should be able to see the HW

ACE is a useful practice/study tool which is now used with multiple textbooks but which was designed around the Wade and Bruice text. You will be able to attempt the homework 4 times before submitting it, but you are responsible for completing the assignments by the deadlines. You may need to get a little practice using “MarvinSketch” the embedded drawing software. Homework will be scaled to 70 pts, and this will be done through online ACE. You will be assigned homework during week: 5.

Services for Students with Disabilities: If you anticipate the need for reasonable accommodations to meet the

requirements of this course, you must contact Services for Students with Disabilities (SSD,

http://www.unl.edu/ssd/services/ academic.shtml) and request that SSD send me official notification of your

accommodation needs as soon as possible. Please make an appointment with me to discuss the accommodations and how

my course requirements and activities may impact your ability to fully participate.

Phones (texting) and computers must be turned off during the Lecture.
