Objectives: The activities associated with this course are designed to provide students an understanding of the fundamental principles of organic chemistry and to foster the ability to solve problems, to write and speak clearly, and to think critically and creatively.

 

Description: This course will be concerned with the knowledge and understanding of the fundamental theories and practices of organic chemistry sufficient for subsequent entry into programs/courses requiring an organic chemistry competency, the workforce, or graduate professional programs of study. Emphasis will be placed on classification of compounds, names and structures, reactions, synthesis and mechanism; introductory spectroscopy and bio-organic topics.

 

Lab safety: Students must follow all written and verbal instructions regarding safe lab procedures. A written copy of lab safety policies will be provided. Failure to comply with these rules may result in dismissal from the lab. Eye protection must be worn at all times in the lab. Personal electronic devices such as cell phones and pagers should not be brought to the lab with you.

           

Format: The Lab will begin with a briefing in a classroom to be designated by the instructor.
Please read your lab and be prepared with any questions you have regarding the procedure or the written report. During the lab period please concentrate first on completing the required experimental procedures, measurements, and observations. Calculations and questions are a secondary priority if they can be done outside the lab period. These priorities are essential if labs are to be completed. Information for each experiment must be recorded in the lab notebook and initialed by the instructor prior to leaving lab. Reports to turn in will be written from the information recorded in the lab notebook. The format for notebooks and written reports will be provided for each experiment. Because of the importance of the safety in chemistry, students should bring  lab
coat and appropriate safety eyewear. All the experiments will be described in a quad ruler bound notebook (available from the instructor).

 

Federal laws require UNCP to accommodate students with documented learning, physical, chronic health, psychological, visual or hearing disabilities. In post-secondary school settings, academic accommodations are not automatic; to receive accommodations, students must make a formal request and must supply documentation from a qualified professional to support that request. Students who believe they qualify must contact Disability Support Services (DSS) in DF Lowry Building, Room 107 or call 910-521-6695 to begin the accommodation process. All discussions remain confidential.  Accommodations cannot be provided retroactively. More information for students about the services provided by DSS and the accommodation process may be found at the following links:

While exposure to chemicals commonly encountered in a university laboratory setting pose no or low risk to an adult, they can pose a significantly higher level of hazard to a fetus. Many of these hazards are not well studied, and it is not known what exposure level is safe for a fetus. It is therefore prudent for pregnant women to limit the unnecessary exposure of a fetus to any chemicals. This is especially true if the chemicals are mutagenic (causes damage to chromosomes) or teratogenic (causes birth defects and/or fetal death).

 

If you have recently become pregnant or anticipating becoming pregnant while you are enrolled in a laboratory course, please inform your laboratory instructor and s/he will provide, upon request, the Material Safety Data Sheets for the chemicals you will be exposed to during this course. You can then discuss with your physician the potential hazards these chemicals pose to the fetus in order to make a choice as to whether or not to stay enrolled in the laboratory course during your pregnancy. 

 

Evaluation/Grading: Graded assignments will be scored on a 100-point scale. Letter grades for the course will be assigned according to the following scale:100-95=A, 94-90=A-, 89-87=B+, 86-83=B, 82-80=B-, 79-77=C+, 76-73=C, 72-70=C-, 69-67=D+, 66-63=D, 62-60=D-, 59 and below=F. These letter grades will then be converted to the 4-point QPA scale by the University Registrar's Office prior to being recorded on student transcripts (see p. 42 of the UNCP catalog). 

Lab: Graded assignments for this course will include the lab reports (60%), notebook (10%) a midterm test (15%) and a final exam (15%).  All lab reports are due the next week following the experiment. For each day of delay you lose 10% of the grade. Now lab report will be do after 10 days. No lab report can be accepted after the final test in lab.

Attendance: Attendance at all scheduled lab sessions is required. There will be no make up labs. If absence is unavoidable excuses must be written and submitted one week prior to or following the absence. Additional documentation may be required. Unavoidable absences are considered for personal or immediate family illness, death in the immediate family, or business commitments that are verified by your employer in writing. Missed labs that do not meet the above criteria will result in a grade of “0”. No student will receive credit for the lab if he or she misses in excess of two lab periods.  For religious holiday policy please refer to the following website for details: http://www.uncp.edu/chem_phy/religiousholidaypolicy.pdf.   

Honor Code:  Students are expected to follow the UNCP Honor Code (see pp. 51-53 of the UNCP catalog); settled cases involving first-offense violation of the Honor Code will result in a minimum penalty of course failure. Notes or book are not allowed during the test. Only material provided by the instructor can be used during the test.
