Upon completion of Chemistry 250, the student will be able to name, draw, complete reactions, and draw
the mechanism for those reactions for the following classes of compounds: alkanes, alkenes, alkynes, and
their halogenated derivatives.
Required Materials: Organic Chemistry, 6th Ed. by John McMurry; OWL internet access (available in
bookstore); Notebook for notes and handouts, paper, pencils (preferred for exams) and pens.
NOT Required: Cell phones and beepers must be turned COMPLETELY OFF and stored out of sight. If a
student has no place to store a cell phone, a locked desk drawer in the classroom will be made available for
storage of the phone until the end of the class period.
Cell Phone Policy during Exams: The use and display of cell phones during exams are prohibited. All
cell phones must be turned OFF and stored out of sight during an exam. If a student has no place to store a
cell phone, a locked desk drawer in the testing room will be made available for storage of the phone until
the end of the exam (last person leaves). Any student who displays or uses a cell phone during an exam
will be required to sign a form documenting that they have violated the cell phone use policy. If any cell
phone technique is subsequently found to have been used to compromise the testing process, the document
signed by the student and a report by the instructor will be sent to the Division of Student Affairs as a
violation of the Louisiana Tech Honor Code.
Exams: A total of 4 exams will be given during the quarter. All exams are comprehensive (from Ch. 1
through current topic). ONE makeup exam will be given during the last regular class meeting of the
quarter for anyone who has missed a regularly scheduled exam. This will be Wednesday, Nov. 17 or
Thursday, Nov. 18. Thank you for not asking for special favors!
Grades: Grades will be based on the total number of points earned during the quarter: Exams (approx.
90%); In-Class assessments, Homework Assignments, and OWL assignments (approx. 10%). The
following grading percentages are guaranteed:
A, 90-100%,
B, 80-89.9%,
C, 70-79.9%,
D, 60-69.9%, and
F, below 60%.
Makeup Policy: Any student who misses an exam must communicate directly (either in person or by
phone/email) with the instructor within 48 hours after the absence. Direct communication means that the
student involved (not roommates, cousins, significant others, etc.) will communicate with the instructor.
Any student who misses an exam with a valid excuse will take a make-up exam over the same set of
material. The LAST regular class meeting will be reserved for students to take makeup exams. Students
who will miss exams for known reasons such as sports teams, field trips, weddings, funerals, etc. should
contact the instructor prior to the exam and as soon as possible by email, phone, or in person.
Arrangements for an early exam will be made when possible. This is preferable to the end-of-quarter
makeup exam!!! “Not being ready to take the test” is not a valid reason for missing an exam.
Students needing testing or classroom accommodations based on a disability are encouraged to discuss
those needs with the instructor as soon as possible.
Attendance: It is imperative to be in class each day and to be there punctually. You should make every
attempt to attend if you intend to perform well in this class. The classroom assignment points lost by an
absence cannot be recovered; late homework assignments will not be taken for credit. Bottom Line: Be
there! Be on time!!
OWL Homework: OWL (Online Web-based Learning) is a comprehensive, web-based, homework system
that includes the delivery and grading of electronic homework assignments. Students log into OWL
through a web browser and complete assignments selected by the instructor. Students may repeat
assignments as desired to try and better their grade. Please note that there are due dates for each
There will be a total of four OWL assignments. An OWL assignment will be due the same day of each
exam. Students should stay current by working problems from an OWL assignment as each topic is
covered in class. NOTE: We are on CST. OWL is on EST.
Section 001 (TR) OWL assignment 1 is due Sept 23; OWL assignment 2 is due Oct 14; assignment 3 is
