This is a sample syllabus; those for a specific semester may be modified slightly
CHEM 1102 - General Organic Laboratory
For the laboratory course you will need the following items:
1) A laboratory coat: knee-length and long-sleeved.
2) Safety goggles (not Safety glasses!): The laboratory coat and goggles must be worn at all times anyone in the laboratory is doing experimental work. They may be purchased at Researchstores on the second floor of the Science Bldg. (Note: No open-toed shoes are allowed in the laboratory at any time!)
3) A strong, reliable lock: Lock your drawer whenever you leave your bench, even if you only walk across the lab. Lock your drawer at the end of the lab period. You are responsible for any broken, missing or stolen glassware and equipment.
4) A lab manual: "Laboratory Manual, Organic Chemistry, A Short Course," tenth edition, by Harold Hart and Leslie E. Craine, Houghton Mifflin Co., 1999. You are responsible for reading the assigned pages before lab! Pop quizzes will be given!
GRADING:
Lab Experiments: 75% (11 experiments, drop one) All work, both inside and outside the lab, is to be done independently. The copying of lab reports is considered academic dishonesty and will be prosecuted to the extent allowed by the University.
Quizzes: 20% (4 quizzes, drop one) These may cover material from the day's experiment and/or the previous week's experiment. These may be unannounced. Be prepared!
TA Evaluation: 5% A grade assigned by your TA.
MAKE UP LABS: There are NO make up labs. This is the reason one lab grade is dropped.
| Jan. 13 | Orientation, Safety, Drawer check-in. |
| Jan. 20 | No lab. |
| Jan. 27 | Bring your labcoat, goggles, lab manual, and lock.
Read: Introduction: To the Student, pp. viii-x in the lab manual.
Experiment 1, Melting Point Determination: Purity and
Identity of Crystalline Organic Compounds, pp 1-8. You will
use a Mel-Temp apparatus to determine all melting points. |
| Feb. 3 | Experiment 2, Recrystallization: Purification of Crystalline Organic
Compounds, pp. 9-13,17,18. You will recrystallize acetanilide by the
macroscale procedure only. |
| Feb. 10 | Experiment 3, Distillation: Separation and Purification of
Organic Liquids, pp. 19-26. In this experiment, you will
substitute acetone for the hexane and 95% ethanol for the toluene.
You will perform parts 3 and 5 only. All fractions go into the waste
bottle. None are saved. |
| Feb. 17 | Experiment 4, Extraction: A Separation and Isolation Technique, pp. 27-37. |
| Feb. 24 | Experiment 6, Chromatography: Column, Thin-Layer, Gas-Liquid,
and Paper, pp. 49-64. Read the General Principles for each technique.
You will perform parts B and D, Thin-Layer (TLC) and Paper Chromatography
only. You will use commercially prepared plates for TLC. |
| Mar 3 | SPRING BREAK |
| Mar. 10 | Experiment 7, Conformations of Alkanes and Cycloalkanes:
An Exercise with Molecular Models, pp. 67-83. |
| Mar. 17 | Experiment 8, Preparation of Alkenes from Cyclohexanol
and Tests for Unsaturation, pp. 85-87, 91-97. You will prepare
cyclohexene only. |
| Mar. 24 | Experiment 9, Cis-Trans Isomerism in Alkenes: Models
and Experiments, pp. 99-102, 105-106. You will convert
maleic acid to fumaric acid by the macro scale process. |
| Mar 31 | Experiment 11, Electrophilic Aromatic Substitution,
pp. 121-126, 127-128, 133-137. You will prepare methyl m-nitrobenzoate. |
| Apr. 7 | Experiment 14, The Hydroxyl Group: Reactions of Alcohols and Phenols,
pp. 169-182. You will perform tests 1, 4 and 5 only.
Experiment 15, Reactions of Aldehydes and Ketones, pp. 183-202. You will
perform Part A., Tollens' Silver Mirror Test and Part C., Iodoform Test. |
| Apr. 14 | Experiment 20, Synthesis of Aspirin (Acetylsalicylic Acid), pp. 255-260.
You will perform the macroscale procedure. |
