CHEM 350 - Organic Chemistry I Experiments List

Experiment 1: Melting point determinations. Single and mixed melting point procedures are used to determine purity and identity of an unknown organic compound.
Experiment 2: Recrystallization of acetanilide. Learn the steps of recrystallization and assess the purity of your crystals.
Experiment 3: Simple and fractional distillations. Learn how to setup a distillation apparatus and use it to purify a liquid mixture.
Experiment 4: Refractive index. The operation of a Abbe refractometer and its use in the assessment of a fractional distillation by use of mole fractions.
For an online demonstration of the use of a refractometer, please go to University of Puget Sound's Chemistry Lab Techniques (by Dr. John Hanson).
Experiment 5: For tutorial help, consult Organic Acid/Base Separations. Use of acid/base chemistry to perform an extraction on a mixture of organic acid, organic base and neurtal hydrocarbon. Operation and use of a separatory funnel.
Experiment 6: Qualitative organic chemistry for functional groups. Alkanes, alkenes and alkynes. Plus an Infrared Spectroscopy Tutorial. For interactive tutorial help, consult Infrared Spectroscopy.
Experiment 7: Extraction of naturally occurring and optically active compound, usnic acid, from lichen and use of a polarimeter.
Experiment 8: Acid-catalyzed dehydration of cyclohexanol to cyclohexene.
NEW Optional Experiment 8: Acid-catalyzed dehydration of 4-methyl-2 pentanol to methylpentenes. Includes the Remote Lab operation of an online Gas Chromatograph (You must use Internet Explorer Browser to do the remotelab).
Experiment 9: Nitration of acetanilide to p-nitroacetanilide.
