Description: Organic structure and characterization through the study of: Electronic orbitals and bonding theories, molecular modeling using Spartan Plus software, trends and correlation of physical properties with structure, stereochemistry of molecules and stereospecificity of reactions, reactions and reaction mechanisms, application of a series of reactions toward synthesis, theory and application of spectroscopy, and application of chemical principles in the laboratory. Prerequisite: Minimum grade of C in Chemistry 1B. Required Materials: 1. Textbook: David Klein: Organic Chemistry. 3nd Edition 2. HGS Molecular Model Kit. # 1 01 3 A-" Or g a n i cCh e mi s t r ySe tf o rSt ud e nt " ( ht t p : / / www. ma r u z e n. i n f o / h g s / c a t a l o g / p r od u c t _ i n f o . ph p ? p r o d uc t s _ i d =6 16 ) 3.

85-100% = A 73-84 % = B 60-72% = C 48-59% = D

The lecture portion and laboratory portion of this course will have separate final exams. The 150-point final will cover only lecture material and is scheduled for the two hours exam period during the final exam week. You need to get a minimum of 50% in the lecture portion of the course in order to achieve a “C” grade or higher in the course. 1

Exams:

The lecture portion will have the major exams. The laboratory portion of this course will have quizzes. See separate lecture and lab schedules for exact exam dates. Lecture exams will cover the lecture topics and the assigned reading or handouts from lecture. First, exams can only be made up if arrangements are made in advance and if there is a proven valid reason. Missed exams can only be made up before an exam is returned and discussed. Late exams may be penalized up to 20 points.

Attendance: Attendance is required. Absences of more than three lectures will generally result in dismissal from the class. Also lab will keep its own attendance requirements. Canvas:

Important announcements, additional problem sets, answer keys, etc. will be posted on Canvas. (https://pcc.instructure.com/login). Students should log-in at least twice a week to check for announcements.

Homework: You are expected to do most of the problem exercises at the end of each chapter in the Klein’s textbook, assignments in lecture and lab package and additional assignments posted on Canvas. The answers to all problems in Klein’s book will be found in the student solution manual (copies are available in the library’s reserve section). For additional practice, students may also do online problems from wileyplus.com (access to this site is packaged with the new textbooks) and Unit Review Test problems from Carey’s organic chemistry solution manual 7th edition (available in reserve section in the library). Molecular modeling assignments are to be done in the chemistry computer lab using SPARTAN software. It has been our experience, that complete understanding of problem-solving is very important to your success on the lecture exams. Lecture Quizzes: You will have five lecture quizzes covering the topics in lecture and from the book. No make up quizzes will be given. Cheating:

Any form of academic dishonesty, whether it occurs inside or outside of the classroom, will result in a score of zero for that exam, quiz, or assignment and may result in dismissal from the course. If, in the judgment of your instructor, one student knowingly allows another student to copy from his/her paper, both students will be punished.

Drop Deadline: It is the student’s responsibility to withdraw from the course. Check the schedule of classes for drop deadline. Cell Phones: ***Cell Phones must be turned off during lecture and lab. During quizzes and exams the cell phones must be put away in the backpacks. *** No recording of any type is allowed in lecture or lab unless you have explicit permission from instructor.

CHEMI STRY8 ALABORATORY Description: Laboratory to accompany Chemistry 8A lecture. The laboratory topics will include melting point determination, recrystallization, distillation, extraction, chromatography, refractive index, spectroscopy, preparation of products on a microscale level. Molecular modeling exercises using PC SPARTAN will be done to understand the concept of structure and bonding, conformations and MO theory. The CHEM 8A final grade is determined by total points in both lecture and laboratory sections. Required materials:  A college ruled notebook  Lab Book: Anne B. Padias - Making the Connections: A How to Guide for Organic Chemistry Lab Techniques. Ha y de n Mc Ne i lPu b l i s h i n g , 1st or 2nd edition.  Laboratory Safety Goggles (to be worn at all times in the laboratory)  Recommended-A laboratory coat or apron Quizzes:

Quizzes will be given during the lab lecture period and will cover laboratory procedures, experiments and handouts. Calculators may be needed. No make-up quizzes will be given.

Attendance: Attendance during all lab lecture and laboratory session is expected and required. Absences equal to or exceeding 12 hours of lecture and/or laboratory time will generally result in dismissal from the course or receiving a grade no greater than a D. Failing to complete the check-out procedure with the stockroom for whatever reason will result in a $20.00 fine and a hold on your records. Laboratory Assignments: Lab reports will be due at the beginning of the next lab. Five Points will be deducted for any lab reports handed in late. All reports that are more than one page must be stapled. Reports will not be accepted more than a week late. Notebooks:

It is essential that you keep your lab notebook current and that you enter all data directly into the notebook. To make sure of this your lab notebook will be checked periodically in the lab.

Academic Dishonesty: All experimentation and laboratory analysis is to be performed individually unless specifically approved by your instructor. Any copying of information from another student or any form of plagiarism is forbidden. These, as well as all other forms of academic dishonesty that are detected, will result in your immediate dismissal from the course. Safety:

An organic chemistry laboratory can present some serious hazards that can lead to injury or death. Unsafe practices and behavior will not be tolerated at all. Any student 4

who is deemed a hazard will be asked to leave the laboratory and a grievance will be filed with the dean.
