    TEXTBOOK / SPECIAL MATERIALS:
    1. Text:  Organic Chemistry by Francis A. Carey & Robert M. Giuliano, 8th edition.  This text will be used daily in class, as well as for homework assignments and general reference.
    2. Lab Manual: CHEM 133 Lab Manual. A.J. Gaier. DACC custom lab manual. Fall 2016 edition.
    3. Laboratory Notebook:  A bound laboratory notebook with duplicate sheets will be used to record data in lab.  The recommended version is the spiral-bound, 100 page carbon copy notebook from Hayden McNeil Publishers.
    4. Safety Goggles:  Students must purchase their own laboratory safety goggles and are available in the DACC bookstore.  They must be splash goggles with the side protection and NOT safety glasses.  Acceptable eye ware will have "Z87" stamped on the side.
    5. Calculator (Optional):  Any simple scientific or graphing calculator is sufficient.  A calculator may only be necessary for small portions of the class. 
    6. Enclosed Shoes & Pants:  For lab days.  If you are not dressed properly you will not be allowed to participate.

    EVALUATION:
    Grading is based on a weighted percentage of five different categories with overall grade divisions at 90, 80, 70 and 60 percent.  The five categories are:  four or more midterm tests accounting for forty percent of the course grade, fifteen lab reports accounting for twenty percent of the course grade, ten quizzes accounting for ten percent of the course grade, classroom work accounting for ten percent of the course grade, and a final exam accounting for twenty percent of the course grade.  Attendance is required and a student may be withdrawn from the class roster due to unexcused absences.  Laboratory work must be performed during the regularly scheduled laboratory period.  "Make-up" laboratory work at an alternate time will not be an option.  No credit will be given for laboratory reports submitted if the student was absent from the laboratory session.  If a student has a valid excuse for missing a lecture or a laboratory class, credit for the missed period may be arranged with the instructor and will not be automatically given to the student.

    Notes:
    All students must pass the laboratory portion of the class in order to pass the course.

    The final exam will include all material covered in the semester.  Every student is required to take the final exam at the scheduled time.  Each student must take and pass the cumulative final in order to pass the course.  

    A curve may be applied at the instructor's discretion.
