Supplemental Work
Optional reading is listed at the end of every chapter of the textbook, and in the supplemental bibliography provided. Additional homework problems may be found in the textbook and in any other inorganic chemistry textbook, many of which may be found in the chemistry library, room 104, Musser Hall.

Objectives
In order to successfully fulfill the objectives of Ch 242, the student must be able to define basic terms, to perform appropriate calculations, and to demonstrate a mastery of the basic principles of physical chemistry as applied to the study of structure, bonding and reactivity of main group and transition elements. Various aspects of these areas include, but are not limited to:

1. The understanding and prediction of molecular geometry and structure according to principles of valence bond and molecular orbital theories of chemical bonding.

2. Acids and bases: theories, applications and structural correlations, with particular emphasis on Løwry-Bronsted, Lewis and HSAB principles.

3. Ionic solids and the application of thermodynamics to the prediction of stability and other properties.

4. Covalent compounds and the application of thermodynamics and kinetics to the prediction of stability and other properties.

5. Molecular symmetry and point group predictions for simple systems.

6. Chemical forces, including London (Van der Waals), dipole-dipole, ion-dipole, and hydrogen bonding (inter- and intramolecular), and Fajan’s Rules.

7. Determination of molecular structure and aggregation from colligative properties and basic chemical and physical methods.

8. Main group elements: descriptive chemistry, nomenclature, bonding, structure, and reactivity.

9. Transition elements: descriptive chemistry, nomenclature, bonding, structure, and reactivity.

Ch 242 laboratory is a continuously evolving vehicle to introduce chemistry majors to many techniques of experimentation and instrumental methods under conditions and in contexts similar to those in which a practicing chemist might encounter them. The student will become acquainted with a variety of standard synthetic methods and techniques of product purification and identification. The student will need to gain experience in the recognition and application of proper separation and purification procedures, such as distillation, sublimation, chromatography, recrystallization, and extraction. Finally, there will be considerable emphasis on structure determination, particularly through multinuclear NMR and infrared spectroscopy. The major objectives of the laboratory portion of the course are: (1) to develop synthetic skills in the application of certain specialized procedures, such as inert atmosphere manipulations, vacuum line operations, high and low temperature syntheses, photochemistry, and use of small scale equipment; (2) to become proficient in the use of multinuclear NMR and IR spectroscopy for product identification; (3) to become a mature and independent laboratory worker; and (4) to use the chemical literature effectively.

Attendance
Regular attendance at lectures is required of all students. You are responsible for everything that is said during lectures and laboratory, including material that is introduced from sources other than your textbooks. Minimal preparation for lectures consists of reading the assignments before coming to class and writing out all of the assigned homework. Regular attendance at laboratory is also required. Each experiment must be conducted during the week it is scheduled. Students are required to complete each experiment; failure to do so will have a negative effect on the final course grade.

Problem and Reading Assignments
Responding to questions and problems in frequent and serious study sessions 
can be one of the most effective learning techniques. Examinations may contain questions similar to those in the homework. If you delay problem solving and studying until just prior to the quizzes and examinations, you will be asking for trouble.

Examinations and Quizzes
Examinations will be given during lecture periods on the indicated dates.  Under no circumstances will these examinations be rescheduled. Brief quizzes will be given during lecture periods. The dates and topics of the quizzes may or may not be announced in advance. A comprehensive final examination will be administered at the end of the course during the final examination period. Attendance at exams and quizzes is required; there will be no make-up exams or quizzes under any circumstances. Unexcused absence from an exam or quiz will be rewarded with a grade of zero.

Grading
Examinations and quizzes will be graded on a scale of 0-100%. Letter grades corresponding to these percentages follow.

0 - 59% = F
60 - 69% = D
70 - 79% = C
80 - 89% = B
90 -100% = A

Final grades will be determined by combining examination grades (40%), the final examination grade (20%), a composite of quiz grades (15%), and a laboratory evaluation (25% for written reports and performance). Other factors, such as improvement during the semester, will also be considered. Letter equivalents to the final numerical total follow.
 

0 - 59% = F	70 - 72% = C-	83 - 86% = B
60 - 62% = D-	73 - 76% = C	87 - 89% = B+
63 - 66% = D	77 - 79% = C+	90 - 92% = A-
67 - 69% = D+	80 - 82% = B-	93 - 100% = A

Students may request a grade of "I" by submitting a formal written request to the professor of that course.  Grades of "I" are assigned for extenuating circumstances only.  They are not given simply to allow additional time to complete required course work or to improve a course grade.  Forms are available in the Registration & Records Office.

Written reports are required for all laboratory projects. The due dates for these reports will be announced in class. Reports should contain the following sections: introduction, experimental, results, discussion, and references. The experimental section should be written in a style similar to that used in The Journal of the American Chemical Society. For additional information, consult the most recent edition of "The ACS Style Guide," J.S. Dodd, editor. The discussion section of your report must address the questions listed in the descriptions provided for the various laboratory projects. The reports, which will be graded, should be as concise as possible. Only typed or word-processed reports will be accepted. Students are required to complete all laboratory experiments and written reports; failure to do so will result in a failing grade for the course.

Laboratory
Students must maintain a written record of all laboratory work related to this course in a hardbound notebook with permanently numbered pages. All entries should be in ink. One of the major challenges of this course will be to maintain a complete, accurate, and well-organized research notebook. This notebook should be a complete report and record of your work. In the hands of another chemist, it should enable him or her to reproduce your work exactly.

Each student is responsible for maintaining cleanliness and order in the laboratory, and each is expected to share in maintaining cleanliness and order in sinks, hoods, and general use areas.

Lockers are stocked to provide the special equipment needed for this course. Do not pilfer equipment of any kind from a neighbor’s bench or from another laboratory.

Students will use many of the major instruments available in the chemistry department. It will be the student’s responsibility to learn the proper use of these instruments, to leave them in the appropriate stand-by or shut-down mode, and to remove all materials when vacating the area. Report accidental breakage or malfunction to the instructor as soon as it occurs.

The scheduled laboratory hours for this course are from 12:30 - 3:20 p.m. on Monday and Wednesday. Students are expected to conduct work during this time. Students may be admitted to the laboratory during evenings and weekends by the student assistant in the chemistry library only upon the presentation of a permission slip signedby the course instructor. The student must also sign in and out using the log provided for recording evening and weekend laboratory work.

You must complete all laboratory experiments and reports to pass the course. The last date for laboratory work is indicated on the schedule.

Academic Integrity
Students are expected to be familiar with the policy regarding academic dishonesty and plagiarism as outlined in the College’s Student Handbook, and in the most recent edition of the pamphlet, "Academic Integrity at Elizabethtown College." These activities will not be tolerated, and will be penalized severely.

Disability Statement
If you have a documented disability and need reasonable accommodations to fully participate in course activities or meet course requirements, you must:  (1) contact the Director of Disability Services, Dr. Kristin Sagun, in the Center of Student Success, BSC 228, by calling 717-361-1227;  and (2) meet with me, the course instructor, within two weeks of receiving a copy of the accommodation letter from Disability Services to discuss your accommodation needs and their implementation.  Students must bring to my attention accommodations they may use in order to complete this course.  Students will be accommodated as law requires, but remember, by law, inititation must be made by the individual student, not by the instructor.

For the Record
Illness and Family Emergency.  Since absence will negatively impact learning, contact the instructor promptly in the event that work or related obligations are unattended or incompleted.  Make sure that you obtain notes from classmates on all missed materials.  The decision as to the nature of any makeup work is entirely at the discretion of the instructor.

Note: All work and reports must be completed prior to 2:00 p.m. on Friday, April 24, 2009.
 
 

1. Protective eyewear is required.  If glasses are worn, they must have attached side shields.  Contact lenses are discouraged and in themselves do not fulfill the requirement.

2. Wear suitable attire (e.g., no shorts or skirts, only closed shoes but no sandals, nonflammable clothing, etc.).  Wearing of a lab coat or apron is recommended.  Tie back or secure long hair.

3. Know the location and operation of all laboratory safety equipment.  Use the fume hoods as much as necessary to minimize the presence of undesirable vapors.  Keep your face out of the hood and keep the  hood window down as much as possible.  If the need to use a safety shower or eyewash station arises, insure sufficient washing or irrigation time and volume to mitigate the problem.  Irrigate the contaminated eye until the problem is corrected, making sure that the eyelid is pulled back to expose the eye.  If a chemical  is spilled on you, wash the area immediately with water.

4.  Be familiar with the chemical properties, physical properties, and toxicity of the  substances with which you will be working.  Ask your instructor to direct you to the location in the chemistry library containing this information.

5.  Wear gloves if reagents are toxic, corrosive, or if there is any doubt.

6.   Create & maintain a clean and orderly workspace appropriate for the environment and compatible with the experiment in progress.  Anticipate the consequences of your actions and plan all work accordingly.  It is also your responsibility to insure that your laboratory neighbors act in like fashion.  Everyone assists with cleanup at the conclusion of work.

7.  Exercise caution when transferring reagents in order to minimize the potential for spills and for contamination of the bulk supply.  The incorrect manipulation of container lids is also a common source of contamination.

8.  Place waste chemicals in appropriate containers labeled with the contents.  Consult an instructor for further details on proper disposal techniques.  Place discarded glass only in the special containers designated as such.

9.  Use an open flame in this course only when directed to do so.

10.  Transport liquids or solids only in closed containers.

11. Always be on the lookout for pressure build-up.  Never heat a closed system.   When extracting with a separatory funnel, always vent the pressure before and  after shaking.  It is prudent to begin an extraction in a beaker or a flask where there is plenty of room for gases to escape.

12. Never distill to dryness.

13. Use only round-bottom flasks or filter flasks for evacuation.

14.  Use extra caution in manipulating heated objects, especially ironware and glassware.

15.  If there is an accident, regardless of how minor, notify the instructor immediately.

16.  Eating or drinking is permitted only outside the laboratory.

17. Think while you work and use common  sense.  Never rush.

18.  Perform no unauthorized experiments.

19. Never work alone.

20. Further specialized instruction will be provided as specific experiments warrant.
